Images in Bookmark Cards Not Rendering Properly in Gmail

Hello all,

I’m running Ghost 3.30.1 in a droplet on Digital Ocean.
My URL is https://rootededu.com

Tomorrow, I’m hoping to send out a weekly newsletter recapping the week. I sent a test email to myself and found that images in bookmark cards did not render properly in Gmail on Chrome (most recent version of Chrome on macOS). The images render just fine if using Gmail in Safari, Firefox, and Edge. The images also render just fine in Spark and a few other email clients I tested.

Here’s a comparison of Safari vs. Chrome—

Anyone else experiencing this issue?

Thanks!
