I verified my e-junkie and google checkout settings. Doesn't seem to be any issues with my settings, or options for mandating an e-mail be entered.
I did notice, however, that for standard google checkout orders, I receive a customer name, a @checkout.google.com email address, and an address. For these MobileUsers, I do not receive a name, do get a MobileUser-XXXXXXXXXXXX@checkout.google.com address, and no physical address (it shows my business address as theirs instead).
From this, it almost seems like google is providing an e-mail address to you guys just like normal, but not collecting any information from the actual buyers, so the e-mail is never forwarded to them. Any ideas on how to get beyond this?
Sorry for the delay in response, but I hadn't received any MobileUser orders in a wihle and thought maybe the issue had worked itself out somehow.
