Can not open a office document: please check you permissions

[jakobroehrl]

On some office Documents I get this message in the Android App:
Wrong office document message: Document can't be saved, please check you permissions

I only get it, if a lot of users write on this file.
In the browser is no error, every user can write in this file.
It seams like a file lock, because every user has the right permissions.
I can solve this problem if I restart the complete server or if the users opens the file in a browser, then the lock is away and the user can open it without the error in the app again.

Android version

3.26 and 3.25

Nextcloud server version

I saw it on 26 and 27

Maybe it is related to
nextcloud/richdocuments#3169
nextcloud/server#40090

Does the fix in nextcloud/server#40090 (comment) resolve this for you?

[jakobroehrl]

Can not test becaus of #12338
But I think 40090 could fix this problem

[joshtrichards]

I saw your update on the other issues. Did those resolve this for you as well?

Im not sure, it does not come up again till now
