A family of Microsoft word processing software products for creating web, email, and print documents.
Same exact issue. I can open an almost blank document by clicking on General notes instead of New blank document. Idiotic. I am glad this is just a trial of Microsoft 365, because it is way more hassle than it's worth.
If you are using the Office app and it generates an error message, the workaround I suggested earlier in this thread applies: create a new blank document from within the full version of Word instead of using the app.
You can use the Feedback facility to report the issue with the app to Microsoft.
