Proton Calendar not syncing or notifying

ash

I have both ProtonMail and ProtonCalendar installed via Google Play Services. Push notifications seem to be working find on ProtonMail, but not consistently with ProtonCalendar. In particular, I typically get notifications from ProtonCalendar after a recent restart (so it seems to be running on startup) for events in the morning, but it seems to stop running in the background at some point.

I've set battery usage to unrestricted. I've checked all the permissions (Network permission is on, all Notification permissions are on). I've tried enabling "Exploit protection compatibility mode" to see if that helps, but no dice.

What am I missing?

Mine are working fine. By chance are you forgetting to add the actual notification (email and / or push) when you add something to your calendar?

ash I use Proton Mail and VPN with the 3 Google sandboxed apps with network, and no probs at all. I use Simple Mobile Tools Calendar and works fine for me. Don't want to log-in to Google so I use GitHub APKs for all of these.

ash If you don't want to use Google, you can use the infomaniak suite on fdroid, which works very well.

Maybe this will help? https://proton.me/support/calendar-notifications-android-ios

[deleted] Thanks, but no. Been through that. All notification permissions are enabled...

I still get calendar notifications and my battery usage is set to Optimized, no denied permissions, Pause app activity if unused is off, allow alternative routing in Proton calendar is set to on.

Not sure if that will help. I have seen weirdness with proton apps where I've had to uninstall/reinstall to correct. Typically with VPN but maybe worth a try with calendar?

Kottonballs Thanks for the suggestions. Will cross-reference settings with yours and try a reinstall if it doesn't work.

Thanks @NightSky, but I have been setting notifications in the calendar.

I think I have it working now. I'm pretty sure something has failed in the past as described above, but after reinstalling and cross-referencing with @Kottonballs' settings all seems well.

Caveat: I think the testing I was doing to check to see if certain settings changes were taking effect was too aggressive: I was setting calendar events with notifications for ₂₀ minutes in the future. These notifications were definitely not coming through - so it could be that I was setting too short a window for the calendar to sync appropriately in the background.

Yesterday, as a test, I set notifications on a bunch of events throughout the day, then restarted the device. After the restart I added another event with notification that wouldn't have been caught on the initial device startup. All notifications fired, so I'm optimistic that things are all good.
