I'm on Windows 11, and now it is worse. Not only do I still lose all the money when closing the app, but had to repurchase all previous upgrades to the booster packs. Every. Time. I. Close. lol So now, I have to wait for my money to return, purchase the old booster upgrades to get to the new milestone of 4B, and if I close the app, do it all over again as it acts as if I never bought a booster of any kind.
Edit: A bit more info about that issue concerning the upgrades that I just learned... if yu stay on an upgrade screen, say for example the Undress upgrade for $150M, and it is greyed out because you do not have enough money, you have to toggle off of it to purchase the upgrade when you do collect enough as the game does not register that you have accumulated the needed amount even when you have the amount now. Not a very big deal as it just takes toggling to a different category such as fellatio and then back to undress, but I thought I'd let you know the tiny bug exists.
Also, second edit: having to repurchase upgrades finally stopped. Now they are keeping for whatever reason.
