Power number stuck on 166w during ride - latest update

Half way through a group ride this morning 4/23/2019, my power number got stuck on 166w and stayed there. All other sensors were still reading, and the trainer was still providing feedback based on terrain, but the power number on screen was stuck. Another rider in the group had similar issues earlier.
Attempted to unpair and repair the trainer, but the issue stayed when I went back into the game screen.
The most recent update installed when I logged in. Had no problems yesterday.
I’m running Zwift on a Macbook Pro. Wahoo Tickr 1st Gen trainer.
