AVP PICKUP AND ACTIVATION.
GOTCHAS:
1. watch out for the timeout on your iphone after initial pairing/setup. lots of screens after it starts, and if you don't get through them quickly, the iphone will timeout and prompt you to SIGN-IN to your AppleID. that means you'll have to type on the ridiculous floating keyboard. for a brand new user (me), this was extremely frustrating as I had to unlock my iphone in a public area, go to passwords and figure out what my actual password is (I have it in muscle memory, not visual memory)
Workaround: ZIP through the initial screens and choose "Setup Later" as much as possible.
2. if you don't have an apple device nearby and must Sign In to your AppleID, it will not work if you are using secure keys for MFA. the messaging about it is quite frustrating, advising you to reconfigure your MFA or _use another AppleID_!!!
Workaround: Don't try to set up your AVP without an iphone or ipad nearby, and see above.
3. iMessage will not work on AVP if you have Contact Key Verification enabled. You must disable it if you want to use iMessage on AVP.
TIPS AND REMINDERS:
* you must get Apple Care in store. you can't get it on your own, later. if you decide to do it later, you will have to take your AVP to the store to have it inspected and then Apple Care to be activated. if you have even the "smallest blemish", your AVP will not be eligible for Apple Care. Choose Wisely!!
[edit: this is what i was told by the specialist. someone below said they could add it after the fact without an in-store validation]
* take your own large bag to put the Apple bag inside of when you leave. The bo and its bag are HUGE and will surely attract attention as you leave.
* choose to STAY at the store, open the box, go through the setup screens, and lock it to your AppleID. call me overly cautious, but it doesn't have FindMy, and without locking it to your AppleID, a thief can resell it.
