So I downloaded the game, and after closing the game and re-opening it, the Gallery is reset, and everything is locked.
I can't recreate that on my end or have any similar reports. Gallery entries are stored in persistence, which is in the same folder all your saves are in. Even if the persistence file is deleted, it'll instantly repopulate based on the variables of the save file, I can do this just by loading the same save again, but you may have to go to sleep or something. This should operate the same across Mac, PC, and Android, but I don't own a Mac, so there's that.
I hope you mean you slept in the game and not real life. If you also can't ctrl to skip then that 100% means your persistence file has been deleted, as "read lines" are also stored in persistence. If your saves are working, which means the app is allowed access to write to your drive, but the persistence file is being deleted and not regenerating, that's something I've never come across as a dev or a player.
