Support Instant Sync/Pull (WebDAV-Push) #1704
Description
Is your feature request related to a problem? Please describe.
When using multiple devices (as an individual, but especially when collaborating), one needs to explicitly trigger sync events to make sure other devices/users see the changes immediately/quickly, and to see theirs.
Describe the solution you'd like
For CalDAV/Nextcloud accounts, it would be lovely if the app supported
https://bitfireat.github.io/webdav-push/draft-bitfire-webdav-push-00.txt - with the goal of immediately sync'ing across devices and sessions.
(There is already a Nextcloud extension: https://apps.nextcloud.com/apps/uppush, https://github.com/nextcloud/notify_push)
Describe alternatives you've considered
The other alternative might be to reduce the sync interval considerably, but this would increase server load and is suboptimal when an event-based mechanism exists.
(The ability to configure the sync interval might be a temporary workaround, though.)
