Improve DoH UI

[manum45]

Do you use TrackerControl from Google Play/F-Droid/other?
F-Droid

Describe the bug
When I configure https://dns.quad9.net as DoH endpoint URL in the trackercontrol advanced settings and go to on.quad9.net, it shows "no you are not using quad9".
If I configure this endpoint in the android secure DNS settings and disable trackercontrol, on.quad9.net shows "yes".
DoH is disabled in my browser.

Does this mean this setting does not work to change the DNS?

To Reproduce
See description above.

You need to enter https://dns.quad9.net/dns-query

I have also tried that, on.quad9.net still shows "no".

I have also tried that, on.quad9.net still shows "no".

Is Wireguard off?

[manum45]

Yes it is off in Trackercontrol.
Private DNS in android is disabled and "block android private dns" is enabled in Trackercontrol.
If I configure DoH in my browser the quad9 page also says "yes", if I only configure it in Trackercontrol it says "off".

https://dnscheck.tools/ also shows that still my ISPs DNS servers are used.
