Yes, I have tried the event “User is logged out” as the manual suggests. It redirects, but not server side as far as I can tell.
I have now implemented a suggestion from a thread linked to a thread suggested above, which seems to fix the issue in at least one of my apps: When creating the Go to Page workflow, the Data to send needs to be left blank.
This I did not see mentioned in the documentation, but found it in the forum.
