1) Have you been prompted by your MetaMask to sign an ETH or BSC TX? If not, try to restart your computer and then visit the UI with the wallet you originally used (MetaMask, etc).
2) Check your MetaMask activity to ensure no pending TX is there.
3) Make sure you added renBTC, etc into MetaMask (as a custom token).
4) Try hard-refreshing the webpage (F5).
