Once you stake a player, it cannot be edited or refunded.
However, if your stake hasn't been filled and the event hasn't started yet, you do have the option to cancel the stake 1 minute after placing it through the 'My Stakes' section of the app.
To cancel your stake:
1. Wait 1 minute after placing your stake
2. Go to My Stakes
3. Select the "i" button
There is no cancel option once the stake has been filled and the event starts.
