My iPad and iPhone recently updated to iOS 26.2. Now Safari on iPad won't open porn sites (at least PornHub and e621) but iPhone will. Both devices are in the same WLAN. I'm in Finland, EU. The operator I use seems to have no effect (I tried DNA and Telia 4G broadband on both devices).
The screenshots are from my iPad. Usually I got the errors in the first two images, but I got the third one once too.
Safari screenshot: Safari can't open the page. The error was: "the URL was blocked by a content filter"
Safari screenshot: website not allowed - e621.net is a restricted website
