When syncing my Bernstein accounts, I get "name or account number has changed for one or more of your accounts" message. Going for four weeks now.
The complete message I get is:
"It appears the name or account number has changed for one or more of your accounts. Mint should automatically discover and reconcile these accounts."
It would be nice if it did, but it doesn't. I have checked the account names and they appear identical to what I have in Bernstein.
