Any blocking can lead to confusing and non obvious results - another reason to oppose ISPs and states doing it. I run a block list (2 million or so URLs in Pihole) for reducing adverting and tracking. The things that happen can be unpredictable and unexpected, particularly because issues are rarely encountered. I wouldn’t be at all surprised if users of this iOS feature have had problems and haven’t known the source or reported them (even when there is an error message).
