My Vanguard accounts stopped syncing about two weeks ago.
The error is:
"Account needs attention (Care code: api.database.accountkey.notfound)
To restore connectivity to your account, you must reconnect to your bank."
When I click reconnect, I am taken to the Vanguard site, I log in and then am given a disclosure to read and agree to enroll. When I click enroll, I am taken back to Simplifi (without being able to select the accounts) where it just spins forever.
I saw some other Vanguard related issues, but this seems different since it only started two weeks ago and has the specific "account not found" api error.
