Co-Pilot refusing to delete chat history and more.

I experienced this on a tablet and I went to my profile in Outlook. Error message says not all of my settings were successfully deleted. 

I then deleted them one by one. While they seem to be deleted, I exited Bing Co-Pilot and signed back in and they were still there. Even a day later.

I replicated the issue on Microsoft Edge and Chrome on Desktop.

It's quite obvious Bing wants to keep your chat history as long as possible and they don't respect your privacy. 

Aside from this, Co-Pilot is incredibly frustrating to use. It fails to follow directions, continues to lie and denies that it does. In rare cases, it acknowledges it did in fact lie. And of course, when you challenge it, it loves to cut you off.
