Hey, @Ashlee_2 !
Thanks for reaching out.
Just to clarify, did you add your social sharing image in Online store > Themes > Customize > Theme settings > Social media? There, you’ll notice a Social sharing image section. This section will always override the social sharing image that you add in Online store > Preferences and this is the case with the Debut theme.
If you’ve added your image in your theme settings, then it sounds like Facebook hasn’t yet updated the information on their end. If this is the case, then I would recommend waiting a couple of days before attempting to post your store link again.
Another potential reason why you may not be seeing any image when sharing your link could be because you are sharing it on Facebook for the first time. Facebook actually has a help doc on images in link shares that offers further information on why this may be the case. There, they state:
When content is shared for the first time, the Facebook crawler will scrape and cache the metadata from the URL shared. The crawler has to see an image at least once before it can be rendered. This means that the first person who shares a piece of content won’t see a rendered image.
In other words, there’s a good chance that this is expected behaviour and the next time you share your link, you should see your image.
I hope this clears things up, but let me know if you are still having issues seeing your image. If you can also include the link that you’re attempting to share, that would help.
Looking forward to your update!
