Site Identity Logo Not Resizing

Hello everyone! I’m working on a new blog called “Camping Cents”, and I am using a logo in “Site Identity”. I am having a problem where the logo will not resize. To get the mobile to appear correctly, I have to make the desktop to small, and to get the desktop to appear correctly, I have to make the mobile too big. I need help with getting my logo to resize for varying platforms. Desktop and tablet are fine, mobile is the issue. Thank you in advance for any help you can provide!
