Huh. I'm also on pc, but it's unavailable right now so I'm playing on my phone. Anyway, what I'm doing if there's an update is I take the save file off and put it aside for now. I tried to have a clean start, but I realized the saved file couldn't be removed because it would just create a new one; I even deleted the game, but it still returned (I don't know if some people have the same thing as me).
Back to what I'm saying. After I take the saved file and put it aside. I download the newly updated version, take the saved file, and put it where it always was in the updated game. I then delete the old updated version once everything is working in the updated version and if it has my progress saved in there.
That's what I've been doing on my pc every time my Gmail notifies me of the updates and I'll just do this to have the updated version.
