Every time I create a step challenge for my team to join, nobody can ever search to look it up. I made sure my first 2 challenges were private, but nobody can ever find them by name, I still have to send an invite. I can’t even get into my mobile app to log my steps, it keeps saying “please make sure you enter both a user name and password”. I enter both and it still gives me an error. I tried uninstalling and reinstalling but no success.
