One time player data reset, sorry
Very sorry but updating to the new version will clear all your player stats and start new data going forward. This won't happen with every update but in this major change over from the old app to the new app it appears this was unavoidable.
I try to do everything I can not to track users or store any data on my side. That means all the data is on your side and unseen by me and I have no way to restore any of it for you.
Again, sorry.
