how can I repair defective URL metadata for Lemmy posts?

cross-posted from: https://lemmy.ml/post/26657745

I've been using Lemmy since last August and I find it very useful for sharing articles.

Most of the time articles are very easy to upload with no real defects. However, there are a few websites, such as apnewsDOTcom that send data that ends up as giving "Just a moment" for the headline, and no thumbnail image. [see https://lemmy.ml/post/26652484]

Where would I look in the apnews webpages to find the data elements that need fixing, and what software would I need to enter the fixed data into Lemmy, so that the Lemmy post looks right?

Thanks in advance for any help I get for this.
