Pi-hole blocking websites on mobile, working fine on desktop

OK, will you please remove all of the extra lists, flush your cache, and try again?

All of the lists you add need to be in HOSTS format, or it may cause issues. We do have logic built in to detect if an incorrect domain is added. The easylists from ABP especially need to be parsed properly. If you're looking to block more domains, check out WaLLy3K's lists.

Did you add these lists via the Dashboard or by editing /etc/pihole/adlists.list?
