Since last update HR data not working

I use my iPhone with a Kickr SNAP trainer. My wheel speed and cadence sensors are Garmin. I use a 4iii Viiia HRM to collect speed/cadence and transmit to the phone (since Garmin won’t enable theirs).

This was working fine until the most recent update. It would occasionally drop signal before (if the 4iii battery got low) but the last few times Ive ridden Zwift since the most recent update it hasn’t worked at all.

The 4iii app shows that it is paired with the Garmin sensors, but Zwift is not getting the data… the synch page doesn’t show the inputs either.

Did you check the batteries in the Garmin sensors? Also, make sure the Viiiiva isn’t paired with any other devices over BLE.
