I wonder if there is a manual refresh limit on the app now, since the update last week. Two of us have been testing on and off. Originally we just went to my status and hit refresh a million times, and nothing would happen until BBG time. Lately, I refreshed less often, my wife refreshed semi-constantly for two test days… both of the recent times I was able to get a join group while she wasn’t. Can’t be sure, but maybe someone else has seen similar issues.
