HI,… i am trying to upgrade to tagtool Pro, but I keep getting an message that transaction could not be completed… (UNKNOWN ERROR)! Other apps could be purchased and installed.
It’s a new IPAD (6th generation) running IOS 11.4.1.
A friend installed tag tool pro in an Ipas Pro with the same operating system… and it’s running wonderfully.
can anybody help?
thanks und vielen Dank

HELLO! It’s solved. Customer Service of Apple modified some issues and made it work.
Don’t ask me what, it’s not specified in their replies, but it’s done.
Thanks and sorry
