jacobgrillo thanks for the report. While I have not experienced this myself, I see this as a valid issue, particularly on slower hosts or when you are accessing a forum that's far away geographically. The longer the server response time, the more obvious this issue might become. Technically browsers already show a loading indicator, but I agree it's probably not obvious enough.
I created a GitHub issue so we don't forget about it FriendsOfFlarum/oauth43
