Mindfulness bell doesn't work – Zazen Suite - Meditation Timer & Mindfulness Bell Review

Do not buy if you want the mindfulness bell. It resets to off. Not just me, other reviews say the same. I specifically bought for the mindfulness bell. Other problem is bell won't go off if phone locks and lowest bell increment is 5 mins. But highest auto lock time is five mins besides never.
