Cadence connection issue

Since the latest Zwift updates (both hardware & software) … i am now noticing that on initial start of my training plans the cadence is not being defected.

Cadense value greyed out, although all sensors on Zwift hub (classic) is detected on initial log in (using PC).

I then have to exit plan or log out and go back in again on training plan and now cadence is working perfectly.

Any ideals guys

Thanks
