Can't delete file on OneDrive for Android - Kindle Fire HD 10

I created a new Word Document on my Kindle Fire HD 10 tablet using the Office 365 app. It created Document (1). I looked for a "rename file"  function but had to settle for "save as".So I have two files. I saw nothing on Office 365 to delete the file. Went to one drive and found it. Tried to delete it there. It tells me that "It will be moved to the recycle bin and removed from all your synced devices." However, it doesn't delete the file and inexplicably doesn't give an error mesaage. This occurs even when the Office 365 app on the Kindle Fire is closed.
