Has anyone managed to get it working? I am evaluating Nextcloud for potential move from ownCloud and neither of them have working locking.
My Nextcloud is freshly installed by AIO, version 31.0.0, Temporary files lock is installed. I tried opening a shared MS Word document on two Windows 11 24H2 computers with client version 3.16.0, virtual files disabled, and it did not work. Office on the other computer did not open the file in read-only mode and was able to make changes to the document. Which then caused a conflict on the first computer while the document was still open by both.
