WaletteConnect is not working on mobile

I implemented “wallet connect” for user authentication in my web application using this documentation https://docs.moralis.io/authentication-api/integrations/firebase-nodejs

When I use a PC and scan the QR code it works perfectly, but when I use it in a browser on a phone and select MetaMask it doesn’t work. The code just opens the app for me Metamask but the modal which allows to accept the connection to my portfolio does not appear.

Could you tell me if I have to do something else to make the connection modal appear in the metamask applicationCapture

I don’t know, it seems like an issue related to wallet connect. Any error that you can see?

no error, the connection on PC is going very well, the metamask application opens and I get the modal to accept or cancel the connection but on mobile there is no confirmation modal
