I have made a factory reset on a Galaxy S4 Active running Android 5.0.1. After reinstalling Runkeeper, I can't log in. The e-mail and password works with my desktop and with a newer phone (Galaxy A71). Any suggestions to what can be the problem?
Runkeeper support had similar ideas. I tried older versions including the one that worked before the factory reset. I also cleared the cache and all data and reinstalled the app. I tried resetting the password. Nothing helped.
