Once an item goes live, it is not easy to make updates to its content at real-time.
When you make any changes on the SKU, image or description of the product, it may change or it may not. Please remember that Jet uses a unified catalog and Jet reserves the right to choose which image/description needs to use. The process is not automatic. Only shipping weight, pricing, and qty are values that can be adjusted without any approval from Jet catalog team.
If you wish to make any changes (text, images) to already uploaded products you need to do-
Submit changes by exporting products to JET
Contact JET catalog team at firstname.lastname@example.org, provide them a list of updated SKUs and request for changes to the content of your listings. While sending this requests, try to be as specific why did you make these changes.
Please note, submitting updates usually do not take products back to under review state
