Guys need opinions / experiences.
So iOS 10 bricked my iPad and it forced me to restore. This means Apple Pay was removed from my iPad and guess what I've used to pre-order my iPhone with!!
How will this work? Will pending transactions be cancelled?
The order is sitting on Apple's servers. The transaction is only pending, because they haven't attempted to take the money yet - but they have the details. The status of the app on your iPad is no relevance to it.
