I have the same problem, I'm sure there is some reasoning to it. But I gave up in the end. I assume you mean addlists on Mikrotik vs pi-hole ?My adblocker seems to only function properly on my PC. However, on my iPad running iPadOS 15.8.2, ads remain unblocked. Interestingly, when I direct my iPad to my Pi-hole's local DNS, ads are successfully blocked. Can anyone offer insight into this discrepancy?
