Incompatibility with com.oplus.calendar: "With sound" property lost during sync #2006
Description
Android version and device/firmware type
Android 16, RealmeUI 7 (Realme GT7)
Steps to reproduce
- Connect a Yandex.Calendar account via DAVx⁵.
- Create a local event on the phone and make sure the "Sound" checkbox is ON.
- Trigger a sync.
- Check the event again — the sound toggle has been automatically switched OFF.
Alternatively, it works the other way around:
- In the calendar preferences (via browser), set a default notification (e.g., "30 min before via CalDAV").
- Create a new event on the server and sync it with the phone.
- Check the event on the phone: The 30-minute reminder is there, but the "sound" is OFF. So you won't get a proper alarm from com.oplus.calendar, except a standard push.
Actual result
All synced events are muted by default.
Expected result
The "With sound" state should be preserved. Ideally, it should be enabled by default if not specified, as silent notifications for calendar events aren't very helpful.
I suspect this "With sound" toggle might be a custom property of the Realme UI calendar app. It seems like davx5 might be overwriting this specific field.
