Ethan Mollick says Claude cannot change a user's email address

Ethan Mollick says on X that Claude does not let users change the email address on their account.

He says Anthropic's official advice is to delete the account to make the change. He contrasts this with Anthropic's reported gains in coding productivity. This is a single post from Mollick, and the report does not include an Anthropic response or confirmation of the account-change limitation.
