@macmanx2 Hey 👋

It doesn't look like this issue is particularly related to Jetpack or the Pexels integration. The featured image metadata is persisted as expected, but the theme would be responsible for the display of the image caption.

Looks like the block themes rely on wp:post-featured-image to show the featured image, which is a decent compromise when moving from an older theme to a new block theme. This block does not have an option to render the caption (credit) however.

For reference, it seems like there is some ongoing discussion around "featured images + blocks": WordPress/gutenberg#27617

I've surfaced your concern in: WordPress/gutenberg#40946
