DNS Privacy is without any effect after a while


New Member
I am using SecureDNS (DOH) for filtering ads in apps. After the iPhone has not been used for some hours (e.g. over night), ads are shown in different apps and the response of webpages is slow. I checked the DNS log and the ping is more than 2000ms. After disabling and re-enabling the DNS Privacy in AG everything is fine again. iOS 13.2, AG 3.1.2 with license. I tried also to change Tunnel mode for split to full without any effect. "Restart when network changes" mak also no effect while the network (WLAN) has not been changed.

Any suggestions?
