Header logo not showing in mobile (but hamburger is)

Hello, I’m having issues with a header image in the universal header - the logo shows up fine in desktop and tablet, but doesn’t appear in mobile (it looks fine when you preview/build in responsive mode, but isn’t there live). Any suggestions? It looks like this issue popped up for a few other people in the forum, but they always figure it out before anyone responds so no hints are posted. thanks for any help!
