[jochenwierum]

I think the problem is not the notify_push app but the notifications app.
See nextcloud/notifications#3035 .

[blueskyfeeling]

Same here after update to 33.0.4. Very annoying ...

[kruthoff]

I suggest to close this issue as the real issue is here. It is already fixed.

[melroy89]

Pr merged nextcloud/notifications#3039

But no new release yet.

[itsgps]

Having this exact same issue - and on a Nextcloud Webdav mounted share having piles of files which are unable to sync.
Not only that having very similar issues to when Client version 33.0.3 Would lock files.
