When I complete a level while playing Pet Rescue on my kindle I don't receive any coins. I am connected to facebook while playing and I also advance when I play on my pc after that, but no additional coins show up.
Hey Pm2004, that's strange. You should be getting them once you've completed a level and regardless whether you're Facebook connected or not. Do you have screenshots of your Kindle where you see your number of coins before and after playing the level?
