The work on the “personal entry point” is the solution for many when sharing the Internet from your iPhone to iPad or Mac, but for a while it doesn't work as it should. Apple already knows the problem and the solution can come as soon as an update to iOS 13.4.
Online sharing from our iPhone has been possible for years. If you are away from home and want to use internet connection with your iPad or Mac, using the iPhone as a "router" is very easy. Your kids can continue playing Fortnite during a car tour or watch their favorite movies, using the internet connection (and using more battery) from your iPhone. With iOS 13, Apple has also introduced improvements that allow any app with the same iCloud account to connect "automatically"
However since iOS 13.1.2 many users complained that this feature is not w orking as it should. Your devices don't connect automatically, or disconnect for no apparent reason, or the speed of communication slows down even though the iPhone is installed. Users contacted Apple's help, who currently tells them that the solution is to restart the work.
