EDIT: YNAB is not hacked. they switched to another 3rd party importer but did not communicate the changes to the end users.
Hey Beige Guitar ! Nope, not hacked. 😄 We sent out an email to users impacted by the switch to Plaid at the end of April. I'm sorry to hear it was a surprise, and you didn't see it!
We were given one month to complete this migration, so starting on April 22nd, YNABers were able to "Get Started" with this migration and Update (re-link) their accounts under Plaid whenever they chose to do so. Now that the month is over though, we've started the migration (and sent an in-app message) for those who didn't go through that process throughout the month.
It looks like one of my colleagues is working on getting those connections fixed up for you! 🎉
For anyone having trouble with a bank connection, our importing team is happy to help. You can report a Bank Importing Issue here, and they'll be in touch.
