Hello, I have activated the app for Android. Unfortunately, various websites are no longer running properly. Location data is no longer displayed in smartwatches. Or Google translations on websites are affected. Or pictures on Amazon are not displayed in the following window, etc. If I switch off the app, everything works smoothly again. Is there an explanation for this?


You enter the DNS server directly in the router, then it is automatically adopted for all end devices.

Hello Jack, that's basically true, of course. But we wanted to make the instructions as simple as possible and easy to implement for everyone - some cannot access their router, etc. 🙂
LG, David from TechnikNews
