Hey, thanks for your feedback.
As for my first question, don’t worry, I got it all working already. What I did was simply re-publish the article in Facebook (under Publishing Tools).
For my question #2, I had this issue before with Instant Articles for WP wherein whenever I added an anchored image in my posts, I would always get an error message that says, “No rules defined for .” What I did as a fix was to add a custom transform rule that would go through the content of links containing images like if they weren’t there, thus only process the images within. This is what I meant by custom rules. I was wondering if you happen to support this kind of feature.
