This is an annoying problem I'm having. I installed AdGuard and whenever I went shopping, couldn't connect to their in store WiFi.

I tried excluding their app from AdGuard and switching off DNS protection, and which DID work once, but didn't work next time I went in.

I tried changing DNS hostnames in the AdGuard app to cloudflare - still didn't work.

I turned off DNS protection again and added the cloudflare hostname (one.one.one.one) into my private DNS settings on my Android phone thinking this might work because I've always needed to have my DNS setting on 'automatic' to access the public wifi in store. Still didn't work.

But here's my problem..

Ever since I added one.one.one.one into the private DNS provider hostname field, I cannot delete it, save the blank field and then just select 'Automatic'. Problem: When I delete the hostname completely, the save button then greys itself out, so therefore I cannot ever save a blank hostname. I can select Automatic with the hostname freshly deleted and blank, but when I go back into Private DNS settings again, the old cloudflare hostname is still there!

So my question is...How do I delete the hostname completely so I ever see it again? I don't want any hostname there now.

Also, when I select 'Automatic', Private DNS status is 'On' and not 'Automatic' as it was before.

Help!
