All my Mail signatures have disappeared and are empty
I use many signatures daily for several email accounts. Yesterday, I noticed that a less common signature was listed, but empty. By last night, all of my signatures were still listed but are empty, including my default signature.
I have updated to the latest version of Catalina and I did a safe reboot, neither of which worked.
Help! I need these signatures for my work. Any other ideas?
