Thank you for reaching out on the community and telling us about your issue. Thank you for providing an update as well. Im wondering here if we'll start off with a fairly standard troubleshooting step if that might do the trick. We can try deactivating and reactivating the account. I'll leave steps below on how to do so.
First thing I'll recommend is to save a backup to revert back to just in case. You can find how to do so down below.
Next we'll try deactivating all of the accounts. You can do so by following the article listed down below.
Once all the accounts are deactivated go ahead and follow the article here on reconnecting the accounts.
Once you've done this let us know how it goes! Depending what you're able to find we'll see what we can try next.
