The % you collect for the Cash Back bonus is determined by your VIP level when it is ready to be collected.

If you have the VIP Status Boost perk active, you will see a Cash Back % that reflects your boosted VIP level. When the perk expires, the Cash Back % will drop down to the non-boosted VIP level. If you want to receive the boosted amount, make sure the VIP Status Boost is active when the Cash Back bonus becomes available.

The upcoming Cash Back bonus will also be lost if the game is reinstalled. Please do not reinstall the game unless requested by a member of the Support team. If they are assisting with an issue they will also restore any Coins that are missing as a result of the reinstall.
