Linkedin displaying wrong social sharing image for Squarespace 7.1 site

Site URL: https://www.rebekahorourke.com/

Hi there, 

My client is trying to post an announcement about her new website to linkedin; however, it seems to be pulling the wrong social sharing image from her site. I've manually uploaded and set the branded image with her logo that we would like to use (see first screenshot - I've added it to the site-wide social sharing section AND to the home page to see if that changed anything), but even after using linkedin's post inspector tool (https://www.linkedin.com/post-inspector/) to try and recache the image, it is now selecting a random image from the page rather than using the preset one that all other social media platforms automatically grab...

Does anyone know what's going on here/how to fix this issue?

Thanks in advance,

Nicole

Did you ever figure this problem out? I'm noticing the same thing -- and I am very much a squarespace newbie. LinkedIn is using a different social image from Facebook and text links.
