Can't transfer data from iPhone 15 to 16.
Just bought an iPhone 16 and having massive problems transferring data from the old 15 to the new 16... It just refuses to work. The iOS for both are updated to 18, so it can't be that issue. Used to be so easy but does it seem like apple has more and more issues out of the box? Like overheating etc... If anyone has any suggestions I'd appreciate it!
