Based on the thread https://forums.garmin.com/developer/connect-iq/f/discussion/6676/comm-transmit-not-working-in-garmin-edge was Comm.registerForPhoneAppMessages removed from Edge devices. However, this would be a very useful feature to offload heavy computations.
So will Garmin add this feature back to the Edge devices, or will makeWebRequest be the only supported method?
