Nextcloud Office comments being very dodgy

Our organization is struggling quite a bit with nextcloud office/collabora with the integrated server app atm. We tried to do some collective editing with about 8 people in a document, but making comments was very dodgy: about half of the comments weren’t posted after “save” was clicked, some disappeared, some didn’t accept updates…

Anyone else having this problem, is there a solution? Is it better with onlyoffice?

(…) with the integrated server app (…)

See the Nextcloud documentation:

This is the default option which works out of the box in most scenarios, however for improved performance it is highly recommended to switch to a dedicated Collabora Online installation using one of the other options.
