Blacky1, recently I tried to renew an ESTA via my ipad.
I got right to the payment point, put in credit card details and then it came up "authorisation not complete due to payment issue"
I waited a couple of days just to see if it had been processed but then I pulled all the ESTA details up again on my laptop - completed the payment info again and 'hey presto' it worked.
My son had the same problem when trying to submit payment details to John Lewis via his ipad.
Probably a coincidence but it does seem strange.
Best of luck - what have you been booking this time then !
