There are some limitations after the mass update
It used to be more flexible when you customize the duration of your workout. For example, you can customize plank to more than 1 minute in the past. After the mass update, it is limited to set the maximum to 1 minute. Likewise, you can customize the break to 5 or 10 seconds in the past. But now, the minimum is 15 seconds. Please fix these as soon as possible!
