Apple is officially dropping iPhone support for web apps in the EU - The Verge::Apple will no longer support web apps in the European Union in iOS 17.4. The company says building the feature would be “impractical” on top of the other changes it’s been asked to make.
So basically this is just apple getting stuck over their insistence to not allow additional web browsers on their iOS devices (if you install chrome/etc it’s just a skin over the safari web engine).
