I envy you.They seems to run out of refurbished 3rd Gen iPad Pro and they gave me a 4th Gen (A12Z) instead. I was pleasantly surprised.
I have a 2018 iPad Pro 11" A12X but it sadly has a cracked screen so no replacement for me.
Did I read that right that they gave you a 2020 iPad Pro 12.9" A12Z? That's not bad considering $119 + tax.
