Metronome shouldn't stop after 40 minutes

Whenever I use the metronome, it stops after 40mins

Hi, to an extent this is intentional for battery saving reasons, but there could be bugs with our implementation. Could you share: - iOS or Android? - Is the app in the background or foreground? Thanks!

Merged "Let the metronome have unlimited time" #919

"The metronome times out after an hour please have it keep going until turned off"
