You are correct. I had the same problem. My solution: Convert all Word365 docs to the FREE OpenOffice Writer app.
OpenOffice download page: https://www.openoffice.org/download/index.html
Once you install OpenOffice Writer: Open it, Goto File >>>Wizards>>> Document Converter and select your conversion options. Document Converter will allow you to convert an entire Word365 folder to OpenOffice Writer documents
What a mess. Glad I got away from MS and Windows years ago.
