Does not receive any callback after signing message.

Im trying to sign simple message using ethers, wallet connect and metamask app on android.

      const provider = new WalletConnectProvider({
        infuraId: '--', // replace infuraId
      });
      await provider.enable();
      const web3 = new providers.Web3Provider(provider);
      const signer = web3.getSigner();
      const signature = await signer.signMessage('Hello World');
      console.log('ok')
      console.log(signature);

It did prompt on my phone to sign but I didnt receive any callback from it. This method works well for other providers such as fortmatic and metamask.

Here’s another workaround (if you’re using web3Modal)

// configure web3Modal 
const web3 = await web3Modal.connect();
const provider = new providers.Web3Provider(web3);
const signer = provider.getSigner()
const address = await signer.getAddress();

let signedMessage;
if (web3.wc) {
    signedMessage = await provider.send(
        'personal_sign',
        [ ethers.utils.hexlify(ethers.utils.toUtf8Bytes(rawMessage)), address.toLowerCase() ]
    );
}
else { 
    signedMessage = await signer.signMessage(rawMessage)
}

Can confirm this low-level way works.

if (connector instanceof WalletConnectConnector) {
  const messageLength = new Blob([rawMessage]).size
  const message = toUtf8Bytes(
    "\x19Ethereum Signed Message:\n" + messageLength + rawMessage
  )
  const hashedMessage = keccak256(message)
  connector.walletConnectProvider.connector.signMessage([account.toLowerCase(), hashedMessage])
    .then(response => {
      console.log(response)
    })
    .catch(error => {
      console.log(error)
    })
} else {
  // original way
