I want to reopen this topic since the new Figma mirror update is awesome! and the use of it has increased drastically. Please consider to resolve this issue.
As a freelancer and designer at an agency, I often switch between accounts. Figma recently already shipped the account switch onto the desktop app and native clients. However, unfortunately not for the mobile MIRROR app. Therefore, I would kindly recommend adding this feature to the mirror app as well!"
