Thanks, Ying, but I’m not seeing where I can set a fallback image. Can you help direct me to where I can upload that? I was messing with some of the different elements and am worried that I may have deleted that block.:-(
You can set the fallback image in the Backgrounds section of the GB Container Block settings. Then, to enable usage of the fallback image, you can toggle the option in the dynamic settings in the Block toolbar.
