I am struggling to get a supposedly connected bank feed working. The bank account appears in the chart of accounts with the "lightning bolt", and according to the bank, the account is correctly configured at the bank. But the account does not appear in the list of accounts on the Bank Feeds page in QB (Desktop 2019, up to date). When I try to then edit the account in Chart of Accounts, I go to Bank Feed Settings and see that Deactivate All Online Services is clicked. When I click activate, QB crashes. I tried the merging trick posted in a forum link, but that did not work - the existing account doesn't get the online settings from the new account that was set up and properly linked. I would greatly appreciate some guidance in how to proceed. The existing account has data for over 10 years from the bank - for obvious reasons I do not want to lose that.

Thanks.

Jack
