website is too slow, many pending transaction and the ui/ux isn’t responsive, sometimes i got bug like can’t click button or my balance is not showing I think we should improve the UI/UX in term of the smooth transaction, cuz sometimes I finish the transaction but the UI hasn’t updated. So I think we should need an update for UI/UX .
