Collabora close document button doesn't save


I’m new to Collabora, so excuse my noobish-ness. I just finished installing it and have the integration into nextcloud worked out, and just tested to edit a document which worked fine. However, when I exit with the little x or go back to nextcloud files overview, it exits the document without saving it or asking to save it. Is there a way to change that behavior and get a “do you want to save”-dialogue before exiting? It would save the people I’m setting this up for - myself included - some headaches.


Ok, so the problem persists. Editing the loolwsd.xml (always_save_on_exit) has no effect, closing the document doesn’t autosave.
