Social Share Image not displaying full-size in iMessage texts

When I text the link to any of the websites in my account, they're displaying as small squares to the right instead of larger preview images above the link like they did in previous months. I've tried other websites not hosted by squarespace and they work fine. Screenshot below shows it working in march and being small now. Also a third screenshot of docebo's social share to show it's not iMessage having an issue.

I was unable to reproduce the issue you mention. I tried on my macOS and iOS devices and the messages show the larger displays.

Are you on Apple hardware/software? Have you restarted those devices recently? Updated the oses? This applies to any system you may be using, not just Apple stuff.

What happens after you restart?

I'm running into the same issue. In February, the social share images were full size and now are defaulting to the small right-aligned images for all my SquareSpace sites.
