I was using LibreOffice 7.0.3 and checked for updates. I was prompted to download and install version 7.0.5, which I did (Mac 64 bit). I find that I can neither ‘Save As…’ for an existing document, nor Save a new one.I cannot work out why.
For further information, I am running this on a late 2020 MacBook Pro, with MacOS Catalina 10.15.7
