Once Friday and twice today the android TR app has dropped the signal from both HR monitor and trainer. This is peculiar to the app because in the meantime Zwift (using ANT+ on on PC) was continuing to receive the signals as usual. My fix was to instantly swipe away and close the app. Upon reopening the app would then quickly find HR and power again, and offer me to resume the workout. I never had to do this in months past.
Another issue, when trying to fix I looked under settings and the phone app would not allow me to disable bluetooth (both HR and power use ANT+). This setting is available on the desktop app, but it’s wishful thinking that it might carry over to the phone. Any reason why, or is an update forthcoming?
