issues with sounds when snoozing

Ok I really liked this app at the beginning. But recently I had issues when putting the alarm on snooze: it would start again at the right time expect that a there’s no sound coming out!!! Quite a problem if you go back to sleep. The other app using sound work properly…
Need a fix!!
in the meantime I’m using another app...

Update: the sounds goes on mute and the alarm doesnt make its job, need a fix!!!
