Warn not saving of workout data due to missing sub

I had a failed renewal of my subscription and proceed fine to do a workout, but at the end I got a message that the workout data won’t be saved because the trainer was not activated.

I checked on my laptop and saw the sub wasn’t renewed properly, I fixed it, kept the mobile open but it seems it couldn’t be remedied and I lost the workout data.

Suggested solutions

a) Either save the data but don’t show to unsubscribed user

b) or at the very least, warn the user that the data won’t be saved, before the workout begins
