A family of Microsoft word processing software products for creating web, email, and print documents.
It is apparently a bug that is for all devices reintroduced with a recent update..
Writing here does not bring it to the attention of anyone who can do anything about it. You are addressing your fellow users here. Microsoft is aware of the problem, though.
I recommend using the Public Feedback Portal. https://feedbackportal.microsoft.com/feedback/forum/fb6d67e3-301c-ec11-b6e7-0022481f8472
Then, once your feedback is posted, copy the URL and then come back here and post it so that others can comment and vote.
Be the squeaky wheel. Keep pressure on.
For more on this using feedback, see my article: This is a user-to-user support forum. -- You can give feedback TO MICROSOFT designers and decision makers on Microsoft Word or other Microsoft Products using their feedback mechanisms, (not here). (This is a link to directions.)
