Add ability to bring up the workout menu mid-ride in tvOS

Sometimes I’ll start to get my own warm up in, but want to do a workout. Right now I have to quit/relaunch instead of continuing an existing ride.

Mykel, thanks for the suggestion.  We’ll try and get a workout select button on the pause screen in one of the next releases.

Awesome! Thanks, Jon. You guys are the best in the business.
