I have a problem with the onlyoffice app 4.1.1 on Nextcloud 17.0.2.
I can edit and change/write MS Word-docx/xlsx files wiithout any issue but the old file format doc and xls is onlx available in viewer mode, so I can not change nothing anymore:
How do I return to the former functions, edit and change even doc and xls files?
Greetings
Daniel
