With all due respect Stefan, this odd response is not very helpful at all. To say that there have been some reports that grammar checker isn't as useful as can be expected is untrue and more than an understatement. There have been numerous reports that
the grammar checker has not worked at all since the update to the new Editor.
To type in: "This is to tests the grammars mistakes in these sentence to see if their fixes." and get zero grammar errors is not even close to "not as useful as can be expected." Try it. Do you think this is acceptable?
And then to 'solve' the problem by saying - just don't use the grammar checker, is a bit bizarre. If grammar checker is not going to work, then it should be removed. Having a broken feature is much, much worse than not having the feature at all?
Feedback has been posted to UserVoice many times; with absolutely no feedback.
Understanding that you are a "Word MVP" volunteer moderator and have no control over bug issues, to say that you just don't use the grammar checker?
Appreciate that you have responded and we will take from your reply that there is and will be no fix to this bug coming anytime soon. This forum has been a colossal waste of time.
