Questions
I want to change my email address.
Your account is linked to the sign-in method you used at creation (Google, Apple, or Passkey). To change your email, update it through your Google or Apple account settings. Passkey accounts are not tied to an email address.
I cannot find the Account section.
Make sure you are running the latest version of Cronos app. The Account section is under Settings on the Profile tab.
