Nothing was declared (other than bug-fixes) that was obviously going to concern/affect me - hence I go ahead!!
After completion, it asks me about "Completion"!
Firstly, it starts by telling me that it now wants "2 factor Authentication" (or something like that)!
It gives you a very minimal explanation, but does supply a URL Link for further info!!
But, but, but, its NOT allowing me to get into the device until I complete the set-up (which includes it) - hence a URL Link is pointless!!
I then discover that I'm required to supply Apple with my Mobile Number!! Sorry, but I'm NOT happy with that!!
However I eventually concede & I attempt to put it in!!
For various practical reasons (mainly associated with the way a certain digit repeats itself) it is MUCH, MUCH simpler to enter (& verify) it as:- 07xx xxx xxxx, rather than 07xxxxxxxxx. The latter version requiring a lot more effort to double-check it is right!!
Surprise, surprise, Apple refuses to accept the "Easy-to-verify" version!!
After getting through that, it then tells me that it has sent a 6-digit PIN (via my Mobile), which I'm supposed to enter. Interestingly it describes the 6-digit PIN as:- xxx xxx.
So they want a 6-digit PIN to include a space (for clarity & checking) but think an 11-digit phone number doesn't require clarity/checking!!
After 5-mins of waiting & waiting & waiting (as well as double & triple checking that I've entered the correct number), I come to the conclusion that I'm NOT going to get any PIN!!
Hence I now have to reverse back &, eventually, discover that I can ignore the so-called "2 factor Authentication".
Try again without "2 factor Authentication"!!
This time it tells me that I've got the Password Wrong - I find this surprising as I did double-check it!! Try re-entering again from scratch - this time it accepts.
Next it tells me that it requires a Photograph of my Credit Card (apparently so that I can used Fingerprint identification to log into my device).
Sorry, but I'm NOT giving away my Credit Card details!
Anyway, fingerprint identification NEVER works for me (I thought I had disabled it) because I have "corrupted/destroyed" fingerprints!!.
Eventually managed to skip that!!
Can't remember if I was asked for anything else but, if I was, I managed to skip that as well!
After, what seemed like a very long time (with a lot of unnecessary effort/frustration) I managed to get my iPad-Air2 up & running again!!
