Describe the bug
Some event notifications do not appear when they should have. This is extremely random -- for example, an event notification from the same calendar/notification category appears, but another event notification from the same calendar/notification category does not. Even though the same calendar/notification category appears on the settings and is active.

Over the last 24 hours, I only have 11 notifications from the app, where on any day I should have at least 13 (see Exhibit C).

I have 12 synched calendars (see Exhibit A) but only 6 of them appear in the notification categories (see Exhibit D).

To Reproduce
N/A - related to notifications. No steps involved.

Expected behavior
Notifications appear when there are notifications attached to the events.

Additional context

Note

I migrated from Simple Calendar (by exporting my settings from that app and importing to Fossify Calendar app). On the previous app, no notification issues were present.

My events are served through CalDav syncronization on a personal NextCloud server - synced through DAVx⁵.

App source: Directly from GitHub (through Obtainium).

If it was working on Simple Calendar, maybe you had some system settings set regarding battery optimization or working in the background? If yes, you have to set it manually for Fossify Calendar and see if problem still exists.

I agree, this could be due to battery optimization.

And you both would be right. I thought I checked everything, but apparently, I was wrong.

Thanks!
