you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. It is odd that you're not getting any errors or notifications. With the update it did switch them over and we've since patched it to not without the user but I do apologize it did switch yours over. One thing that we could try is to deactivate and reactivate the accounts. I'd try this out to se if that might be able to get your accounts back up and running. I'll leave instructions down below.
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
Once all the accounts are
deactivated go ahead and follow the article here on reconnecting the accounts.
Once you get the chance to try this out see if we're able to get the accounts back up and running. Let us know how it goes!
