On a desktop computer, clicked the link for the Peanuts app, logged into Amazon, set it to download to "Cloud only" (instead of one of my Kindles) and hit "Get App". Got my $5 credit email in about 20 seconds.
I had tried the exact same thing last night from a phone browser (different game, but still an Amazon Underground game), and it didn't work.
going to sound dumb but.. where do i set it to download to cloud only?
Edit: nvm i dont have a kindle. i guess this is only for ppl with kindles?
