Can I download an older version on android if my mobile isn’t compatible with the latest version (allegedly) despite android 8.0.0. and 5gig storage?
While you probably can find earlier versions at various APK mirror sites I’m not sure it’ll help you much. I don’t have any actual experience with trying to run earlier versions on Android.
My polar h9 heart rate monitor showing connected but no signal through Bluetooth since the update had no trouble before could be a coincidence any suggestions would be grateful
I suggest that you check the Zwift forums to see if anyone else has the same problem. I don’t know if there is anything in the latest version which could cause this.
