During _every_ session the Android Zwift Mobile Link app drops the game at least once. This happens even though the phone is set to performance mode (no sleep or dial-back), on charger (definitely no deep-sleep), and is kept close to the router. Also checked, and there are no WiFi signal drops either, the app just simply disconnects from the game. The only solution is to force close the app, clear cache and restart, and then maybe it will reconnect, but sometimes even that doesn’t help (and this is really frustrating during a session).
The HRM works flawlessly with other devices and apps, so there’s no issue there.
Device: Samsung Galaxy S7 (G930FD), Android 7.0, Zwift Mobile Link v2.1.8
Please fix as this is unusable this way.
