In Studio :: Countdown / Let's Go CTA

[younglisa]

Per the sprint demo, Alex made the point that it isn't necessarily apparent that the initial activity / challenge screen (before the timer kicks in) is you starting the studio. Suggestion is to have a countdown or a "let's go!" cta to have the user actively transition.

NOTE: I am putting in this ticket to see if we want to prioritize some MVP version of this during our final QA. For now it rests as future phase in the roadmap.
