I have the same issue. I reached out to RBC and they gave the following reply:

"Hi there. We've been made aware of an issue affecting some clients using third party accounting software. This issue may be related to recent updates made to our site. We would recommend reaching out to the software provider, so they can investigate and update on their end"

Can you please forward to Plaid?

Thanks.

I’m getting following message when I try connecting. 

I'm getting the same issue. Was getting the same issue with BMO today too, and then retried adding the BMO one and it said it was successful but the connection actually doesn't get linked. But with RBC I can't even re-add it, just keeps saying login is incorrect.

Same issue here.

Don't hold your breath folks. I also used to have Tangerine accounts linked on YNAB and those have been broken since July of this year after Tangerine did some updates to their website. There has been a support ticket open since late July, with no updates.

Frustrating to have to update everything manually and have been considering cancelling my subscription as the convenience of having to sync everything manually may not be worth it for me anymore. 

I am having the same issue with linking my RBC account. This has been ongoing and I first had issues which prevented me linking on October 1, 2020. I was in the process of a major restructuring of my accounts so I hadn't logged in for 2 weeks. From appearance RBC updating was problematic pre-October 1, 2020 as well as my transactions hadn't updated. I submitted two tickets now, the first ticket last week I was told 48 hours to correct and in extreme cases 72 hours. I submitted a ticket again yesterday because the error changed. Now I am getting incorrect username or password. I was told they are working on it.

RBC is Canada's largest financial institution by a large margin. I know Canadian customers may be fairly minor in numbers compared to US customers but having a financial institution this size down for more than a week seems pretty bad. I already accept the fact that the CIBC connection is poor at the best of time, and that Capital One has never been able to connect. I make adjustments for those. I won't however make adjustments to continue using YNAB for my primary bank.

For me without automatic uploads YNAB is broken beyond a usability threshold. It just becomes a frustration, and I would rather use Excel, pen and paper, or a bunch of envelopes taped to the fridge. I enjoy the platform, and find it really helpful. Unfortunately, I am currently looking for alternate options to replace YNAB now. Hopefully this issue gets attention in a timely fashion before I find an alternative that suits me.

Honestly, if this isn't fixed within the next week or so, I will be switching to another software.  What use is a budgeting tool that can't synch up with your financial accounts?

I've spoken to RBC about this a few times over the past year. Their response has invariably been that they don't really care because YNAB is an external service. RBC has their own suite of tools they want people to use, so of course it's not to their advantage to ensure that people can use 3rd-party tools. Personally, I really like YNAB and have had enough bad experiences with RBC that I'd rather move banks (my other institution has worked flawlessly with YNAB this whole time).

Hello, I am a RBC Customer and linking has stopped for some time. I have  unlinked all my Acoounts and use file importing with no issues.

Also haven't been able to connect my RBC accounts for one a week.  I've submitted a bank importing issue form, but honestly if this isn't resolved fairly quickly I'm considering cancelling my subscription. ☹️

Still getting the RBC made a change message this morning. Somehow other software's are still connecting to RBC though.

Still getting RBC made a change, since yesterday I noticed that there is a note at the bottom of the RBC login page. The note states that they are having troubles with this bank and connection is unlikely to succeed.

I'm not an expert by any means, but I still question the login path change that took place around October 1st. The login used to be www1.royalbank.com and now it is changed to www.rbcroyalbank.com. The www.rbcroyalbank.com address is the main website, when trying to login to the personal banking site the www1.royalbank.com address is used. The www.rbcroyalbank.com is a gateway to several different login locations as can be seen on the multiple options for RBC linking. Of course there are going to be incorrect username and password issues if the main site is defaulting to RBC Investor Edge or RBC-USA for example.

CIBC is also still having issues. It says that I am still connected and updates may take longer than usual. Last attempted update is showing as 15 days ago.

Well, it's been over 24 hours and still no transactions to import. There are some that are cleared that could be imported as well. I guess I'll just have to wait another day or two to let them work all of the kinks out...

Both my RBC and Tangerine connections remain broken. Getting a "incorrect username/password" even though I can log into my bank accounts just fine.

Is YNAB going out of business? Why would such a fundamental feature be broken for this long? The link to Tangerine has been broken for several months after years of no trouble. Every day I'm hearing of a new bank having connections issues with YNAB and nothing seems to be getting fixed in a hurry.

Hey Powder Blue General ! We're here for the long haul. Connection issues can pop up along the way as banks make changes, but I know it's frustrating. We work with our import partners to resolve those as quickly as possible, and improve stability overall.

With the Bank Issue form, our importing team is standing by to investigate or if you've already written in, just reply to the email—and we're happy to check on the current status. I went ahead and sent you a message!

My RBC has as well. It's been mostly connected for a week, but it's only really been syncing correctly over the last 2 days or so. We will see how it is going forward.
