Upgraded firmware on Garmin Vector 3S - After that it doesnt show Watt on Zwift

I have been using my Garmin Vector 3S connected to Zwift. Today my pedals updated to firmware 3.6 and after that it doesnt show watt in Zwift. I can pair it both for power and cadence and i get accurate cadence readings but the power is 0 W. Any ideas?

Hi, I’m on 3.6 and it shows power.
One thing I’ve noticed is the cadence readings are all over the place so I’m using the bike’s cadence sensor which is way more stable.

I have exactly the same issue. The Vectors still connect and read power fine with my head unit but show 0w in Zwift since the firmware upgrade.

Does anyone have a solution?
