@marcusquinn I understand your time constraints, unfortunately I am not able to trigger the behavior you are describing, so this is hard to find a fix for it. Maybe if you have some time, can you describe how one of those apps was setup initially before you adjusted the access control from the groups panel?
@robi Yeah, tried all the LibreOffice sort-of mode settings, the experience on Mac & Windows is not as good as Linux, and I don't need to run a Linux desktop just for Docs, Sheets & Slides.
If LibreOffice & Softmaker collaborated, that would be amazing. In the meantime, I need speed and productivity, and this I feel is a notable option, albeit perhaps for growing influence in campaigning for better FOSS in this area by example and qualified feedback.
@bestknownhost for a start to clarify, are you using an external backup storage or just the local disk for now? Using the local disk may cause disk usage to go up quickly depending on how much data you've put into the server.
