Hello Matt,
Good news - the Saris H3 resistance issue for BLE is fixed in our latest release (50775).
The newer trainers from Saris use a different, and more standard protocol (FTMS) which we were not accounting for on android.
Note: if you pair via ANT+ you will not be able to use resistance. This is because we don’t yet support the FEC Controllable Trainer protocol. The fix mentioned above was BLE (Bluetooth Low Energy) only.
