Your balance can be checked in the accounts section here. If you think your balance is not reflecting the amount you expect, make sure to update your app to the most recent version and check your transaction list.
The currency statement reflects the closing balance that consists of your available funds to spend plus pending transactions, while your app shows the balance of available funds only. We included pending transactions on top of your currency statement for better visibility. More information about pending transactions in this FAQ.
If your in-app balance is greyed out, you can easily enable the balance visibility back, check how it's done here.
