Found a new issue, one that we haven’t had before the upgrade of SCN:
Open a new browser, make sure you are logged out.
Open any Wiki page and click on login. After the login you will be at the root page, so you have to navigate back to the page where youstarted from manually which can take a while.
This was different before the upgrade.
Also, occasionally when you click on login you can see the same page but with different parameters being opened constantly, the pages themselves say “please wait”. One redirect after the other. I can’t see any pattern to when this happens, so FYI only.
