I'm not sure what happened with you, but if you follow the developer's instructions and click "continue" and not load, it works. I had no problems going to season 2.
I very much promise it didn't for me. I got all the right text at the end of Season 1, and then Season 2 simply did not start once I clicked new game (instead giving the infuriating "go play Season 1" message). I expect this is because I am using an emulator to run the Windows version on Android, and the files paths are different to what the game expects.
That is by the by though, I am mostly just befuddled why manually transfering the save file to Season 2 isn't the first fix recommended. It is so easy to do and is about two orders of magnitude faster than downloading the entire Season 1 all over again.
The recommended fix of downloading Season 1 again and the transfering your save file to it before finishing the game again, already requires you to transfer a save file! Why not just skip all that crap and tell people to transfer the save file to Season 2 instead?
Anyway, I'm sorry for the rant lol.
