Gmail is syncing your desktop signature to mobile

It might feel like just a tiny detail, but your email signature actually pulls some weight. Whether you keep it short and sweet or drop in all your contact information, it saves you from retyping the same lines and helps you look a bit more polished while you're at it. Setting up a detailed signature is definitely easier on the desktop version of Gmail than on mobile. But if you haven’t set a mobile-specific signature, Gmail will now pull your web signature and use that instead.
