Currently, after sending an ERC20 token, after it has been confirmed, if you navigate to the home/balances screen it can take a few mintues to see the change. I suspect this is because it is waiting for the rif-wallet-service to fetch the updated price. We should lower the balance of the token so the user sees the correct amount immediatly.
I did not test this with rbtc, but it should also update when sent or a transaction has been executed.
