Seeing frequent notifications: Sync pending - Remote data have changed

Seeing frequent notifications Sync pending - Remote data have changed. Also often seeing the Welcome screen "Your data. Your choice. Take control." despite having the box ticked "Don't show in the near future".

Not sure how to properly debug this or what to do about it. Tapping the notification does open davx-ose and I frequently land on the welcome screen. Pull to refresh does then sync without giving any error.

Part of debug info:

[rfc2822]

Seeing frequent notifications Sync pending - Remote data have changed.

This is when a push notification has been sent by the server to notify DAVx5 about new updates.

However DAVx5 can't run as often as it wants, but is limited by Android. In the time between the notification and the start of the sync, the notification is shown. You can tap the notification to open DAVx5, which will immediately start sync and remove the notification.

Push is an experimental feature. Currently local changes will also cause a push and enqueue synchronization, which often shows a notification directly after a local change, and the notification stays until the next sync. This is annoying, but nothing bad. The notification should not be shown on local changes anymore as soon as #1147 is implemented.

Also often seeing the Welcome screen "Your data. Your choice. Take control." despite having the box ticked "Don't show in the near future".

This is a completely unrelated thing.

Did you go through all screens and do all things that DAVx5 asks for? It will ask as long as you did everything or checked "don't show" on every page.

Which page(s) appear after the welcome screen?

Thanks for taking the time to elaborate on the inner working os push. I am indeed using the experimental Nextcloud UnifiedPush app. Maybe I'll mute the notification. I don't have an issue if sync happens at a later point in time.

After the splash screen I see the Open-source software screen. I have ticket "Don't show in the near future" but this is maybe the 6th time I am seeing it today.

Settings > App permissions does show all checked. I don't think there is anything else I could grant.

It shows every few weeks. Maybe the system clock is modified or something like that? Did you uncheck and check again? Is it the only page that appears after the welcome screen?

Not aware of any system clock modifications. Unchecked and re-checked that option. Yes that is the only page that showed after the splash screen. Will observe this a few days.
