Timer audio stops working after a while

[MatLax]

I just did Molding mobility, the whole Recommended routine's warmup and finally Starting Stretching and at the Butterfly stretch the alarm didn't ring and it didn't ring for the next couple of stretches. I've had this issue for a long time, I didn't notice if it always happens after the same number of exercises.

I'm on a Motorola X Play if that changes anything.

Confirming for Nexus 5 and 6. I do only Bodyweight and it stops working around Pull-ups.

I can replicate this on a pixel 2 XL. Restarting the app is a workaround but not ideal.

Confirming for Huawei Honor6x. It does not work from Handstand onwards if you have a second timed set.
