I don't see any of my events
Calendar Op.2 shows the events stored in your iPhone’s built-in Calendar app, so if nothing appears, it’s almost always a permission or visibility setting — your data isn’t gone.
1. Give Calendar Op.2 permission
If the app shows “Access denied” (or simply nothing), it has lost access to your calendar:
- Open the Settings app.
- Go to Privacy & Security › Calendars › Calendar Op.2.
- Choose Full Access.
Since iOS 17, an app limited to “Add Only” can add events but can’t display them, so Full Access is required to see your schedule.
2. Turn your calendars on inside the app
Open Calendar Op.2, go to the Settings View → Select calendars to display, and enable every calendar you want to see.
3. Check the calendars in the built-in Calendar app
Open the built-in Calendar app → tap Calendars → confirm each calendar has a checkmark.
4. Widen the time range
If only older events are missing, set Settings › Calendar › Sync to All Events (see Why can’t I see events older than a month?).
If your events are missing from the built-in Calendar too, see My events seem to have disappeared.
