For example, just now on my phone (Xperia X Compact, Android 7.1.1) I turned off an alarm by toggling it in the main Clock+ screen before it was due to ring. The alarm icon stayed in the notification area, even after the time at which the alarm was actually due.
The built-in Clock application can't be disabled on this phone; I don't know if that might contribute to the problem.
I would really like to use Clock+ for its dark theme!
