Events with "My status: Not going" still trigger notification

[spacekpe]

App version: 6.19.0 Pro

CalDAV calendar is synced using DAVx^5 app. I think the synchronization is not a problem by itself because Etar calendar app (version 1.0.29) correctly shows the event as declined (grayed out in the Etar) and does not generate notifications. At the same time Simple-Calendar app generates notification for the same event.

Export to ics from Simple-Calendar is here: Simple-Calendar.ics.log Most notably it does not contain ATTENDEE line at all.

For comparion here is the same event exported from Thunderbird: Thunderbird.ics.log It contains line ATTENDEE;CN=Petr Špaček;PARTSTAT=DECLINED:mailto:[email protected] which is why a notification should not be generated.
