To turn on alarms in Calendars, you should enable them. For this, follow the steps below:
- Tap Settings.
- Tap Alert options.
- Select an alarm sound instead of No Sound.
After that, go to the Notifications tab in iPhone/iPad Settings > Find the Calendars app in the list > Notifications > Enable Allow Notifications toggle > Enable all the necessary toggles.
If alarms don't work after that, please contact our team, and we will be happy to help you personally.
