Shouldn't take much longer!
Thanks! I appreciate it. :)
They should transfer over to the new version on their own. On PC they do it for sure and on Android they do so as long as you leave the current version on your phone until the new one comes out. Then, when downloading and installing the new one, it should ask if you want to update the application. Just confirm and it should keep your save files.
If you want to make sure, you can copy the save files via file browser and put them back into the next version manually. :)
