Bug description

Nextcloud 34.0.4 on opensuse leap 16.0

I have nextcloud app note in the phone and I can edit any note in the phone that I have already edited in the web browser (i have the NC dashboard as home page).

I have see that the problem is that this files are locked and the lock remains.
I have check that any note opened in the web (firefox 155.0.1) set a lock and then when i close the tab of firefox the lock remains, so the note can be edited from the phone with the nextcloud app, and can be viewed with the nexcloud notes app, but can't be saved from this last one.
Is reproducible always.

sudo -u wwwrun php /srv/www/htdocs/nextcloud/occ files:lock --status 10368
File nextcloud/server#10368 is locked by text

• Locked at: 2026-08-20T10:17:44+00:00

I have just upgraded the server but the bug was there before and still is there

Steps to reproduce

1. Create a note from the web edit it, save it
2. Close the browser
3. Check the file lock

Expected behavior

The lock should be deleted after I finished editing the file in the browser and then the file should be capable of edit in the nextcloud notes app and saved.

Start by reproducing the web note edit and browser-close steps, then check the lock with occ files:lock --status 10368. Done means the lock is removed after closing the browser and the same note can be edited and saved from the Nextcloud notes app.
