Sign-in not working for certain wallets/browser profiles (Metamask, Firefox)

A summary of the issue

Can’t sign in on Mainnet (or testnet) for the address provided (though I can sign in on the testnet address which is on a separate firefox browser profile) - New issue only recently occurring today.

Clicking “sign message on wallet to continue” does not provide the metamask prompt to sign the message for me to be able to continue into manifold studio. Metamask says that it’s connected to Manifold already.

The odd part about this issue is that another browser profile is signing in normally.

I’ve already tried clearing all browser data, completely disconnecting on metamask, and trying again for the problematic wallet.

Can you share a screenshot of what you see?

Do you have any other extensions installed? There is a known bug for Coinbase wallet which causes issues with login if you have MM and Coinbase Wallet installed.

I was not able to make a screenshot as the issue seems to have resolved itself (or a fix was pushed) since I posted.
