Proposed Solution

If you’re encountering issues when MetaMask is not installed, consider adding a fallback or error handling mechanism to notify users that MetaMask is required for that specific login method.

The support team will review your information and get back to you soon. If you have any further questions or details to add, feel free to share!

Hey @betnow this was the expected behaviour, it only used to show the wallets that are injected in the user’s browser context. Please upgrade the version to latest version, the behaviour has changed where if the wallet is not installed, it’ll show the Wallet Connect QR code.
