Re: Edge exists on iOS? Really?
The age restriction is from the Apple store. Every browser in there is rated "17+" since you can access the naughty bits of teh Interwebz with them, and even Apple cannot restrict THAT usage for a mere browser. (It's enforced by the age setting in the used Apple account. Yes, you can lower the age setting if you give a device to your kid, or if you share your account with your family. No, I do not know how well this is working, how secure it is, or how easy kids could hack that, since I am an adult by my lonesome and never needed to meddle with that.) Further, the age restriction set in the App Store is, AFAIK, only for downloading and buying, not using (there may be something age restrictive for using, too, but, well, see above.)
