Question: Upgrade trouble going to 3.28.0

Indeed, the label issue and the ‘update available’ message are the same as reported here:

As mentioned there, the issue with labels might be caused by cache or an outdated language file. (If you are using a custom PO file, you’ll need to add the new translations for the new labels)

The ‘update available’ message is a bug (Int. ref.: Jira ).

Regarding the user view not loading, could you try creating a new view manually?
