Sharing options in extensions
I am having trouble sharing with email directly from Preview. When I click the share icon, there is the option to share via Messages, AirDrop, and notes, but no email. When I go to Extensions in system preferences, I find that several options are grayed out and I cannot change them. What am I missing? Thanks for your help.
