1st - I feel my devices get disconnected from network more often, according to Pihole web UI I have the default 24 hours of lease time, I don't get why this happens more often than before.
2nd - I have a TV box from my ISP provider that only works if I use my Router DNS I tried to add a new line to my 03-dhcp-options.conf but the device doesn't work, I suspect it's still using the unbound DNS instead
(I've split your post into a new topic as it doesn't contribute directly to the Community HowTo, but rather is a request for help with a combination of Pi-hole and unbound (which the.original topic doesn't consider at all)
Also, you are asking for help with a different container altogether, i.e. you are not using Pi-hole's official image, but seem to be running a third-party image containing Pi-hole and unbound.)
