Images no longer sharing on Facebook

Anyone else now having problems with images when sharing a wix dynamic page on facebook?

This used to work fine, but now the image either doesn't appear on the facebook page or it shares some strange image with "business graphs" instead of the image it should deliver.

On my dynamic page, I specify the image I want shared on social under the page settings/SEO/which image do you want to share on social?

It then is supposed to pull the image from my database. This used to work perfectly, but no longer works.

Looking at the Facebook share debugger (https://developers.facebook.com/tools/debug/), it appears that Facebook sees the image that wix is delivering, but doesn't like the format. See for example this response from the Facebook share debugger.

Provided og:image URL, https://static.wixstatic.com/media/b48a30_d248c09222e64457b74c83fb662707e4~mv2.jpg/v1/fill/w_1000,h_523,al_c,q_85/grandchildren%20social.jpg could not be processed as an image. It may be corrupted or may have an invalid format.

I have also tried many things, for example setting the image dimensions to Facebooks preferred ratio (1.91:1), but nothing seems to work.

I'm also now having problems with images when sharing my router pages on Facebook.

This is a core part of my site offerings, so any help would be greatly appreciated.
