OpenWRT NextDNS Resolution

tl;dr: I'm having an issue with iOS clients using NextDNS on OpenWRT.

I just installed OpenWRT on my router yesterday and everything went well. Except my iOS devices are unable to resolve anything when connected to WiFi. If I explicitly add a DNS server to my iOS devices, they are able to connect but not if I get the DNS server from DHCP.

I found this thread to be very similar, which Olivier was responding to:

https://forum.openwrt.org/t/configuring-nextdns/52466

Below are the value output from Olivier's questions in that thread.

root@dave:~# nextdns version
nextdns version 1.10.1

I have removed the NextDNS packages from LuCi and re-run the NextDNS installer located here to no avail.

I'm hoping to get some other eyes on what I need to do to get this issue sorted.

Thanks!
