The timer misbehaves, a feature you miss, the coach features you are waiting for: write here, a person answers.
Before you write.
What helps for a timer problem?
The phone or computer, the browser, whether the screen locked or the tab went to the background, and what the timer showed when you came back.
Is there anything to pay for?
No. Workouts is free; the coach features are not for sale until they ship, and the waitlist is just an email.
