I recently spent way too much time on syncing my Scoutbook and my.scouting accounts.
After syncing with my.Scouting via a SSO, Scoutbook does not provide any form of positive feedback that you have completed this action. The SSO page reads just like it did prior to synching. It does not indicate that you are already successfully synced.
I recommend some form of positive feedback/indicator that an active connection is already established. Otherwise, it feels like the SSO is not present. I understand that upon successfully completing the sync, a brief pop-up indicates it was successful. However, future trips to the SSO page do not indicate the previous success.
Please let me know if you need more information.
