Many such cases - Lemmy.ca

I think most of the complaints are that Microsoft Office doesn’t work. Which is true. The web version of Microsoft Office is honestly kinda terrible.

And no, people don’t want to use a product that does the same thing as Microsoft Office, they want to use a product called “Microsoft Office”. No, it’s not logical, and doesn’t make any sense at all but it’s how people are.

If only libreoffice had an app for mobile platforms…

Being unable to open the documents I wrote on my computer without using some kind of crappy ad filled third-party app is annoying.

Libre Office has a mobile app. The one called LibreOffice viewer is only a file viewer but works perfectly if you only look at documents, it is developed by the same foundation that develops LibreOffice. If you want to edit, Collabora is the name of the app, it is based on LibreOffice and is officially approved by The Document Foundation. It is developed by one of their certified collaborators. Both are available on Android and iOS.
