    BIG OL HOT TIP for folks like me using PiHole to block ads and trackers etc *and* devices on the latest iOS:

    You’re gonna want to turn off “Connectivity assist” right tf now.

    This feature used to be helpful when the wifi genuinely had no internet connectivity, but apparently iOS 27 uses it to *re-request DNS queries that failed because you intentionally blocked them*.

    This feature bypassed my filters for **132MB** of ads and trackers while I was hunting this down 🤬🤬🤬

    The ads themselves get served by neutral CDNs so this was 132MB purely of JSON and cookies over the span of… maybe 24 hours?

    I’m fuming…

    @thure not sure if the functionality is identical, but ios18 has "WiFi-Assist" under cellular settings.
