Thanks for the quick reply David. We’re using Smush so I turned off lazy load for SVGs. That seems to have fixed the issue. When I reached out to Smush support to troubleshoot the issue, they helped me figure out the root cause. I misunderstood how to configure Generate Press theme options. I had inadvertently left one sticky header option off and hadn’t defined the mobile logo file. At one point I think I saw an option to use the header as the sticky header – or something like that. My assumption was it would “inherit” the header logo for mobile too. In any case, the logo’s displaying correctly now with lazy loading enabled in Smush too.
