I am just wondering if this is a problem or just how the game goes, but on Puzzle Swap when I use my Play Coins to get puzzle pieces I get more pieces that I already have then new ones. If I am lucky I get one new piece and the rest are ones that I already have. Today I didn't get anything new. Is this normal?
Yeah, that's normal. When you use your Play Coins to get a puzzle piece, you get one randomized piece from any puzzle that you have started but not completed, which means that yes, you can get pieces you already have. Of course, the more slots on a puzzle you feel up, the more likely it is that you'll get a piece you already have.
