I reported it in V.5.3 not blocking ads that v.5.2.1 blocks on tablet (Android 9)
I have not switched anything it has Cloudflare by default and it’s not secure in new versions for some reason. Then I tried AdGuard DNS and Blokada one that didn’t work. I installed beta version it’s the same but Blokada DNS in it is secure for some reason. So it kinda works.
