Our updates do not remove career cash and game progress.
There are a few ways that game progress and data can be wiped from your phone, one is by manually deleting the App and then re-downloading the new update another is by clearing the games data.
Both things we cannot control with an update and sadly, once lost, career cash and progress cannot be restored.
Game data and progress are also device specific and cannot be transferred between devices. There is no way for us to access a users individual game data as we do not host this information which is why we cannot help restore any lost Career Cash unfortunately.
