I have the same issue for days now and I feel hopeless. The logo appears on every page EXCEPT the home page. WHY??? I deleted 100 times and re-added, I published when I deleted the logo then re-added and still no use. I played with the size, I added a retina logo to see if anything happens and I played with that too. In the end NOTHING worked. I tried to do @humanistischnet solution too but I don’t know what the TinyMCE editor is and I couldn’t find it anywhere. I also tried to find a logo option in the classic editor but I found NOTHING. I even added a featured image thinking that could be the logo but NOTHING. Please help. I’m asking god right now because it seems like it will take a miracle to fix. I am considering remaking my website on a different theme but I am hesitant because I’m not a website builder, I already spent so much time on my site and I even paid someone $1000 to build it and get me going with it (and they can’t figure the issue either).
