The RandomRecurrentTrigger is not working correctly. The logs show that the timers for the triggers are set successfully. however, only some of them get triggered. I added here two examples of the log I'm getting.

Test 1: In this specific test, only 1/7 surveys got triggered

flutter: [CAMS DEBUG] RandomRecurrentTriggerExecutor - timers has not been scheduled for today (2022-3-16) - scheduling now
flutter: [CAMS DEBUG] Random sampling times: [11:43:00, 11:43:00, 11:42:00, 11:44:00, 11:44:00, 11:42:00, 11:44:00]

flutter: [CAMS DEBUG] RandomRecurrentTriggerExecutor - creating cron job : 41 11 * * *
flutter: [CAMS DEBUG] RandomRecurrentTriggerExecutor state is set to resumed

Test 2: In this case, only 2/5 of the surveys got triggered

I tested this several times both with the app open and with the app running in the background, and seems to be a common issue. This didn't seem to be an issue in the past, so not sure what is going on.

The trigger is not being triggered on iOS in the long run. When the app is used over a weekend.
