What happen to my previous Coins?
Effective 1 November 2021, your Coins are now known as 'Stars' and all your remaining Coins as of 31 October 2021 will be multiplied by 4 into Boost Stars.
For example, you have 300 Boost Coins as of 31 October 2021, with effect from 1 November 2021, you will have 1,200 Boost Stars instead. This is a one-time launch reward.
