Riding TDZ stage 1 long yesterday and around 1/2 way I noticed that the trainer resistance wasn’t changing with Zwift Play or Click changes. Gear indication on HUD would go up and down but no response from trainer. Fortunately I was in a virtual gear around my FTP and made it to the finish.
As I passed through the finish banner, trainer returned to selected gear and both Play and Click controllers worked normally.
