Doesn't work?

[timcrob]

Summary:
I downloaded this plugin here from GH and uploaded it to the WP backend (I'm using WP version 6.5.x). I created a meta app and requested oembed read permissions. My app was approved, and I added my App ID and App Secret to the Writing section of the WP backend.

Expected Result:

1. The existing IG embeds throughout my blog would update to display the IG post embedded in my blog (not the grayed out "View this post on Instagram" message).
2. When I paste an IG link into a new blog, it will embed the post.

Actual Result:

1. IG embeds throughout my blog don't update and the grayed out "View this post on Instagram" persists.
2. When I paste an IG link into a new blog, it returns the error "Sorry, this content could not be embedded."

@Ayesh please advise. Thank you!
