We are aware of a bug that causes the pause menu to lose functionality and are working to get this resolved.
We have identified that this happens when the game is paused during a track change, but how often this happens seems to vary from player to player and only seems to affect certain workouts.
If you experience this issue, then please try the following workaround: If you need to pause a class after a track has ended, wait for a target to appear at the end of a runway and then pause the workout. This will successfully pause the class so you can take a breather in-between tracks.
We understand that this isn’t the most convenient solution, but we hope this helps while we work to resolve this issue.
