I am having this same problem, but going into a protected mode did not help.  I still can't see it.  I can see my account listed in the Banking menu, but no option to update.  If I select Manage Selections, it says I don't have anything linked and if I Link the account, it opens a new account instead of giving me the option of using the one I have already.

The banking menu shows my QB balance and a zero balance for the bank balance.  Also says it is updated as of 11/2020, but I have imported transactions through 3/13/23.
