Misuro B+ not displaying Watts

Hi, I’m using an Elite Nova Force manual trainer with the recommended Misuro B+ sensor. The Zwift app is picking up the Cadence rpm from it but the Power Source from it is displayed as Zero (0) watts. The avatar is not moving in the app and when in the game I’m getting a message at the top of the screen to say “Paused”.
Can anybody help please?

Sounds like something else has picked up the Power device, assuming you’re using Bluetooth. Perhaps another app on your phone?

Thanks Steve, I appreciate your reply. I will look into that to see if that’s the issue.
