We recommend taking extra caution and reviewing all deposit information before submitting.
That said, deposits that are still eligible to be cancelled can be cancelled within the app. First, open the sidebar and select the 'Activity' section. Tap your pending deposit, and select the "Cancel Deposit" button at the bottom of the screen.
If you do not see a "Cancel Deposit" option, then this means your deposit is no longer cancellable and is already in the midst of being processed.
