Hello @kmc,
Thank you for your message.
We noticed that the snippet you added was in CSS format (please refer to the screenshot: https://prnt.sc/wejcoMlLIA8), whereas it should have been implemented as a PHP snippet. We have already corrected this on your behalf.
Additionally, we attempted several configurations to apply exclusions for specific media IDs on your page; however, these efforts were unsuccessful. As an alternative, you may consider disabling the native WordPress lazy load feature via the Theme Options panel. Alternatively, you are welcome to submit a request for further customization.
If your primary concern regarding this topic has been resolved, please feel free to mark the topic as solved.
Best regards,
Jack Richardson
