Can't connect XOSS cadence sensor

I can’t connect my XOSS cadence sensor to Zwift through Bluetooth.
I tried through my Samsung A70 .I can see the sensor in my bluetooth list of connections.
I also tried to change batteries changed between the speed and cadence sensor.
Have same problem using laptop. Once in a while it recognize the cadence sensor but it’s not stabilized.
What can be done?

I have the same problem. Anyone have suggestions on how to fix the problem?
