I recently started using OnlyOffice for collaborative editing of a “docx” file using nextcloud sharing on a server maintained by Grenoble university (UGA). It is VERY annoying that quite often (10-20 minutes) the connection to the cloud breaks and the editor announces “The file version has been changed. The page will be reloaded.” then it gets stuck there, it never reloads the file! I have to close the window and reopen it, then reactivate the reviewing mode and go back to the file position where I was working. I consider this a goof fat bug, and from some comments I see I am not the only one affected, I found a post of 2020 with not solution given. Actually the problem occurs also in the desktop editor (which I installed in the hope that would not happen in a local editor).
Is there a fix for that? Otherwhise this bug is a killer for the program, sorry.
