This is why I have my rpi4 set up as 1) a Pi-hole, 2) Wireguard VPN host and 3) DHCP DNS server on on my home network. That as long as I am connected to the VPN from my phone I get no ads. If there's any kind of network issue at my house I can just disable the VPN on my phone. This also has a side benefit that I can use my phone's wi-fi hotspot to remote into my work machine at home as needed.
