Why recommend a third-party app when the OS already has built-in support, that allows you to use VPN with NextDNS configured on Private DNS setting simultaneously? From what I see the only reason YogaDNS is there is because Windows don't have built-in support.
Martheen because not all versions of Android have the "Private DNS" feature. It's since Android 9 that there is native support for this feature and surely some people will still stay on that version... so it's only fair to give it some chance. I have Android 11 and I have no problems, but on the other devices there is Android 7/8 and I don't have support except thanks to Intra!
