When you first connect to your Blocto wallet, you might experience a delay when Blocto is setting up your wallet. If you get stuck on this screen for a while and the spinning circle just keeps going, this is happening because the Polygon blockchain network is congested and responding slower than normal. Unfortunately this is out of our control as it is one of the side effects of using any decentralized blockchain network. You can safely close your browser and try to claim/connect again at a later time and hopefully the congestion will have subsided.
