OK I follow you now. So, some luck here!
I already had a PIN, so I tried resetting the PIN to a different one, and restarting the app.
No change in behavior.
I then removed the PIN entirely, then restarted the app again.
This time the server settings showed up right away! I was able to change my storage location at that point.
I’m not going to re-add the PIN since that seems to be related to the problem, but I’m happy this is resolved for now at least! Thank you for your help.
