Just a tip for those transferring from the old Joiplay to the new Apk version on Android, at least for me. SD Maid would not work I needed to use File Manager from File Manager Plus and the new APK folder did not appear until I opened the game for the first time and created a save.
I then simply copied the entire Joiplay save folder and replaced the new APK save folder and it worked flawlessly with 0 issues or bugs!
