Dear Community Specialists,
this answer is a joke, isn't it?
It's close to "just re-install Windows".
I have the same problem:
iTunes: Latest update, Firefox: Lastest Update, Java: latest update and of course PC reboot.
In iTunes:
App bought (clicked on buy, logged in, confirmed "do you really..." with buy and after that a second time logged in., then clicked on Clickandbuy).
Firefox starts, Clickandbuy window opens.
Locked in at Clickandbuy, everything comfirmed, message received:
"Sie haben dem Anbieter bereits eine Easy Collect Autorisierung erteilt."
(You already gave the seller an Easy Collect authorization). I did a lot of times, but iTunes gives a **** about that!
Clicked on continue and then the magic happens:
Firefox jumps to: http://www.apple.com/itunes/affiliates/download/
and there I receive this wonderful message (with my iTunes open!!!):
"To download the item you just requested, you need to have iTunes."
Thanks for this wonderful message!
I can't buy any apps! (for iOS "only", I can for android, but that's a different story 🙂)
With or without spyware / tracker blocker, that doesn't make a difference.
My only solution now: "buy another phone", do you have a better solution?
Would be great to know!
Many thanks in advance!
