Keeps turning sound off by itself during workouts – Tabata Timer and HIIT Timer Review

Thought this was a good app with customisable features until the app kept suddenly turning off sound by itself in the middle of a workout! The app is updated on my iPhone 7, and Couldn’t find the cause. When it happens it doesn’t stop until I restart the app. This has been happening on different days now and it’s quite frustrating if you’re trying to be timely with your workout and make sure you don’t rest too much between sets.
