If you saved changes to an individual title without publishing, then updated the same title as part of a bulk edit, that title will continue to show "Published-Changes Pending" by default. Publish that title individually, then any updates made using the Bulk Editor tool will be reflected accurately in the Status column.
Please allow at least 2-3 days for any changes to take place at SMD/SMP (it could take longer depending on how many titles you have updated) and feel free to spot-check your product pages at either SMD or SMP after 3 days to ensure your desired changes were updated.
If your bulk edited titles have not been updated at SMD/SMP after more than 7 days, please send us a detailed email to [email protected] and we will be glad to assist.
