I got a new 15 pro max about a month ago. I’ve never had issues setting up a new phone until this one. I used the cloud backup and the main issue was that it wouldn’t take my 4 digit passcode to continue setup. I have used the same # for years. I eventually got locked out so I had to restore the new phone from my laptop. It took forever to download that onto the computer but it did eventually work. Beyond frustrating though.

Another issue with this phone was getting it to pair properly to my car and also to my Enbrel auto injector. Finally got the car done but still can’t pair to the injector.
