Hi Andy. If you are not seeing the folders you created I would guess that you are running V1.00 of the app which didn't have folder support. Please be sure you are running the current version of Crossword and let me know one way or the other if that solves the problem. You can determine the version you are using by going to Settings -> Games -> Crossword on the Playdate.
Thanks, Bob! I was on v1.50, but I just updated to 1.60 and confirmed (both via the game itself and via settings) that I was on 1.60.
However, when I connected as Disk Drive again and looked at the Data folder, I saw the aforementioned com.bwit.crossword folder and a user.xxxxx.com.bwit.crossword folder and when I moved the three puzzle folders (and their puzzle files) to that folder, I now see the puzzles! Yay!
Maybe there's something unusual about my PD setup, but all seems good! Thanks!
Andy, I'm glad you got it working and I'm sorry about that. The difference seems to be how the game is installed. If installed via the play.date web site it has the user.xxx prefix which is not present if installed via USB.. So there is nothing wrong with your device and I'm sorry for not thinking of that.
