Issues connecting to a decentralized exchange (DEX)
If you are using MetaMask to access a Decentralized Exchange (DEX) such as Pancakeswap or Uniswap, and you see the error message "Permissions request already pending please wait", please try these workarounds, which should help you to reconnect:
Disconnect from the site using the method explained here (available for both Mobile and Extension), then return to the dapp and click 'Connect wallet'. Afterwards, retry connecting to the dapp.
If reconnecting using the above steps doesn't work, you could also try reinstalling MetaMask and restoring. Please ensure you have your Secret Recovery Phrase and the seed phrases of any imported accounts safely backed up before uninstalling your wallet.
