Editted... yeah read below.
Hey guys I'm posting mainly because I'm extremely confused. I've been following these issues over the last few weeks knowing good and well with my app just finishing up I'd be going through the same.
I'm confused because... I had no problem whatsoever. I'm here to report that with AIR 20 I've been able to successfully submit my application through Application Loader on a Mac (sent to apple...still waiting approval) ....with every single step coming from a Windows machine... granted today I just went through the whole creation process of certs/p12 etc.... so it was new/fresh. and YES I'm including ANEs specifically (Distriqt's Adverts & Share) and (Milkman's GoViral).
I will report back if my app is approved by apple.
OK YEAH EDIT... apparently I was confused and assumed the issue would reveal itself during the Application Loader process... but no, the issue happens when they reply to you!
Sorry to give anyone false hope... Yeah doesn't work for me either.
