If you're trying to connect Request Finance with MetaMask's mobile app and the connection appears to be stuck in a loading state, it may relate to an issue with an existing session in the MetaMask wallet. To resolve this, follow these steps:
Open the MetaMask mobile app
Go to Settings → Security & Privacy
Select "Clear Privacy data"
Go back to Request Finance in your browser
Refresh the page
Click "Pay Now" to try connecting again
If the issue still persists, please try using WalletConnect instead.
