Ordered during the presentation, per time stamp in upper right corner of image. Live in EST time zone. Still no code after an hour. There is no way you are sending out codes in the order you received the purchases and Google fully controls the mail distribution of the codes.
I received my Stadia package just now but there is no way to use it yet as I do not have my invite code.
I contacted support and they informed me it will be 24-48 hours before all codes go out, hopefully it arrives soon.
That's the missing proof
I ordered on Jun 7th, the controller gets here tomorrow but still no sign of a code being sent to me
