Logo and Site Title/Tag Line are not Showing

Hello, I changed the logo and site title/tagline but it is not showing when you go to my site. Here is what I did, I clicked on: Appearance Customize Site Identity I put in my title and Tagline I uploaded a photo for my logo (I used png and jpeg) Saved info. When I click "visit site" from the dash board, I can see the change. When I log out of wordpress and put in my site name it looks as though no change was made. There is no title/tagline and the word "logo" is showing when it should be my picture. I'm not familiar with coding. Please help me understand what I may have done incorrectly. Should I have checked off certain boxes? How do I get my logo (picture) and title/tagline to appear in the header? Thank you tytenishaosgood.com 4.3.1 version Simple Catch
