This is not my experience. Pihole works flawlessly for me and it’s sitting in my closet connected to my cable modem. Haven’t touched it in a year. No broken mainstream sites and I’m blocking telemetry and other crap from apple, Amazon, google, Netflix, Hulu, Wyze, etc. related to advertising and device analytics trying to profile my usage. Pi-hole has been a blessing in the war on privacy and targeted advertising.
