Xiaomi redmi note 8 and garmin sensor

Hello, i’d like to give Zwift a try during this quarantine time.
I have free rollers and bought garmin 2 Speed & Cadence Sensor with ANT & Bluetooth and I m trying to run zwift on a xiaomi redmi note 8.
If bluetooth is ON, zwift recongise both sensors, but when in game speed and cadence is always ZERO so my avatar is not moving.
I discovered my phone runs ANT too, so I tried to disable bluetooth. In this case only cadence sensor is detected and not having speed can’t go forward to the game screen.
Anyone with simular problems ?
Thanks in advance.

try to download anttester on your google play, and you need to dowload antplugins + antradioservices. and let app permissions to use hardware (ant hardware). it will helps

The option use ant hardware is not present in my redmi note 8. Any idea?
