So you've pretty much been waiting ONE day...Holiday here yesterday...I wouldn't be at all concerned yet then.
I got an approval after 6 days so be patience / a lot of other peoples have also applied and these days google is very strict in giving the ID'S
Whoa, are you serious? People waited three months for an email back from Google? And I thought a week was long.
Congratulations but you do not need to worry so much, even if you are not accepted from the first time, you can still reapply. I wish you good luck with your project and keep us updated with your work.
