I’ve turned off Reminders for shifts but they are back on in my Device Calendar

If you’ve turned reminders off, they only remain off in the MyShiftPlanner App. If you copy your shifts to your device calendar via calendar sync, your default settings in your device calendar still apply. eg. Google Calendar adds default alarms of 2hrs for events, 24hrs for All Day Events.

To remove these notifications, turn off default reminders in your device calendar settings.
