Hi, i have a problem ...when i set , in reminder settings, the first set interval on 15 seconds it's all okay, the snooze is perfect..when i change this number, , for example on 30 seconds, it doen't work or it only works once, it sounds the first time and then silent, i only see the popup without sound but does not repeat the notification sound every 30 seconds.., if you return the first set interval to 15 seconds it will return to work! Why? can you help me? I have a Galaxy S8 with Android 7.0...
