Hi Darla,
Thanks for your suggestion, unfortunately this did not work.
I discovered that the issue was caused because I created a staging site, which also sync’d to square. The versions therefore updated against the staging site, and when I returned to the live version of the site, there was a version mismatch.
I corrected this by deleting all the square meta data from the products, essentially indicating to square that these were all new products, and then deleting the catalogue in the square store. So essentially I started over and re-uploaded the entire store. Not sure if there was a simpler solution?
