Yes, there is currently a bug causing a delay in the balances updating. In the meantime, you can always confirm your transactions by using a block explorer. Simply copy/paste your receive address into the interface. If you can see the tx confirmed in the explorer, it has already arrived at your address, the delay is just the balance updating in the app, which will be rectified soon. For eth based tokens use etherscan.io, for OMI/Go based tokens explorer.gochain.io
