What to do to get rid of the square around faces?

[Pammaw]

When I try to post a picture of a person from my gallery to Facebook, the person has a square around their face,I did all the things other people said to do,but when I went back to gallery I could not find a menu to turn off face tag,the only way I finally got it off in Facebook was to press the face tag then I had to put someone's name in there which I didn't want to do,so how can I get this square out,I have a galaxy Note 9 thank you

This is coming from the FB app, and you can't really turn it off. It should only show, however, when in 'tag' mode (little tag icon on the top right corner of a picture that shows the names of people tagged or, like what you're seeing, squares around faces for tag assignment); turning the mode on/off should show/hide the squares.
