I used to be on a different tablet and I got an Amazon kindle and I found trials on the appstore so I logged into uplay after starting it up and it said at the account I had was on a more recent update than mine even though I haven't used the account in forever (8 months I think? A year?) And I just downloaded the app. I don't think there is a way for me to update through the appstore. It would be a shame to lose all my progress. Do I have to get to a certain point in the game before I can get all my progress back?
