About a week ago I set up my Google Checkout account. I didn't have a specific app in mind at that point but I knew someday I would. Then I downloaded the free version of Robo Defense over the weekend. I decided to buy the full version this morning. After I clicked through the legalese and all that it gave me the usual "check your notification bar for download progress", but it hasn't done anything for 15 minutes or so. No download progress or anything, and the app isn't installed. Does it normally take a while to start the download of a paid app (or your first paid app)?
