Going around Windows Store I managed to trigger an error "Something happened and your purchase can't be completed."
Maybe I am too much of an power user but this message bothers me.
Did problem happen on my computer or remote server? Is author of application at fault? Do I even have connection to server? Am I in wrong region? If I try again will it help? Should I try again now or at some later time? Is error already reported to someone or should I report it?
So many questions and just a short unhelpful message to answer them all...
