I am using Logseq DB on a Mac. While trying adding properties, I am not able to add User Name and User Email, so far, others properties seem to work, including my custom properties like Bother and Body.
I am not sure if my understanding is correct but I did log-in.
In addition, I thought the User Name and User Email should be properties for my cat - Cau, not myself. So when I created a page for Cau, I could assign his email and name.
