iOS Seems to get "stuck" on NextDNS even when reconnected to excluded wi-fi network

Hello,

I use NextDNS for my mobile device when I'm disconnected from my home WiFi - and at home I run pi-hole with some of my own DNS entries.  I have a DNS suffix for all my local entries, `home.lan` - so for example, I have like `computer1.home.lan` - I find that sometimes NextDNS appears to not be disconnecting on my phone when back on my excluded WiFi - so my phone requests the DNS for these entries and fails (because NextDNS can't resolve them, only pi-hole can).

Anyone have any idea how to fix the profile so it immediately stops using NextDNS?
