Spell Check not working in Word 365 after automatic update

Charles Thanks but all of this has already been tried several times for the past 2 months. 

When you type in this sentence, does grammar checker work?

Grammar and to some extent spell checker have not worked since Microsoft updated Editor.   This is not an isolated incident, this is a universal bug.

The grammar checker is on and the language is correct.  

This is a major bug that Microsoft needs to address.

These suggestions are all very well and thank you;  but they have all been tried together with the Microsoft fix and  reinstalling Office 365.  The fact is that Spelling and Grammar don't work on Microsoft Word.  Period.

Now, can someone please at Microsoft organise to fix this bug.  Thank you and goodbye!.

Grammar checking finds ZERO grammar errors in the above sentence.  This is inexcusable.  This issue popped up months ago and not only has it NOT been fixed, it hasn't even been acknowledged as a bug.   100% inexcusable.  And finding no grammar errors in the above sentence is embarrassing.    Here's a suggestion:  REMOVE GRAMMAR CHECKER.  Better to have no grammar checker than to have one that doesn't work.  And seriously, Microsoft created the bug with an update when they changed the Editor, you mean to tell me they can't fix it?  This is beyond ridiculous.

Did you look to see if you have grammar checking for this sentence turned off?

Put your insertion point in the sentence, i.e. in the word "their." and press Shift+F1.

What do you see about the language setting?

This is certainly not something I manually changed. There is the potential that it happened after editing and saving a Word document in another language. Otherwise, I'm guessing it happened after an Office 365 update.  Any idea how/why this would be automatically changed?

The thing that makes this seem so perplexing is that the setting to not check spelling or grammar is a character-level setting, not a document setting or a setting for Word as a whole. If text with this setting is copied and pasted, it can carry the characteristic with it.
