WAC Azure App Proxy disabled URL persisting?

I had a test with using WAC with the Azure App proxy but ive now disabled my Azure App proxy connector and also have also uninstalled WAC and reinstalled and also recreated the Azure App for WAC but the problem ive still got is that for some strange reason MS Edge Chromium is still redirecting my internal URL to the old Azure App URL which no longer exists but i cant find where this persistent redirect is on my WS2019 Instance with WAC installed as a Gateway server??  The only way to access WAC now in MS Edge is to use In-private session which lead me to clear my complete browser cache but the redirects still persisting?

Any ideas anyone?
