I am using Muslim Pro premium paid version and my smart phone is Lenovo K6 Note.
The Problem is unable to play the notification tone on the prayer time, I am using Long Beep as my notification tone, nowadays that is not working properly,
A Notification message is shown in the phone notification bar, but no sound.
I have tried to reinstall the app two or more times to fix this. After install, it will be working for some days, but again same situations.
Can you please check and correct the problem.
