As a web developer, what on earth does this mean? > desktop sites are now the default in Safari Surely it's not some kind of meddling with the device width to make responsive web design even more confusing. That would be very odd. My hope is that it's some kind of user agent manipulation that thwarts device sniffing so you don't see a mobile phone stylesheet or get redirected to a mobile site while using your iPad.
Yep, that's it. Even major websites have this problem, with YouTube being a particularly bad one. If you have an iPad handy try loading up YouTube, then do a long-press on the reload button and request desktop site. It's a much better experience. I don't have the betas, but I expect Apple is applying this automatically based on viewport size. Full screen Safari instance? Desktop page. Narrow viewport in split or slid…
Wow. I've somehow missed this little gem. I usually requested the desktop site via the share sheet option but this is far nicer. Ditto for a quick way to disable content blockers. Thanks!
