Non-response (or delayed response) to sendTransaction requests

### What is this about?

Hello,

We are using the WallectConnect react-native web3modal SDK to request signatures from MetaMask in our dApp.

Our dApp users frequently encounter situations where there is either no response or the response is very slow when requesting a signature. When the MetaMask mobile application is opened via deeplink, it doesn't take any action, which we have to cancel the request.

It seems that manually ending the WalletConnect session in the MetaMask app settings, or manually disconnecting from the dApp (by removing the stored deeplink), and then reconnecting and requesting the signature again resolves the issue.

---
I received a response from MetaMask stating that the issue is due to delays in the WalletConnect relay feature. Also, I've left an inquiry in the WalletConnect discussion https://github.com/orgs/WalletConnect/discussions/4290

I want to know if there are any upcoming updates related to WalletConnect implementation.

Thanks!
