If you have any warnings or errors, you will see them by going to the Feeds > Meta Shops page and clicking “Manage Meta Feed.”
Then click on the warning/error symbol as shown here to surface the current errors:
A modal will pop up with warnings and errors:
Our warnings/errors are color-coded.
Errors (red) indicate that the product cannot be imported into your Meta Shop in its current state and should be addressed immediately.
Warnings (yellow) indicate that the product listing could be improved and/or minor changes Thrive made in order to successfully sync your product to Meta.
For individual fixes, click this box to open up a new tab for that product, where you can make the change, save, close, and come right back to working on the next error message.
We will automatically sync out those fixes every hour to your Meta Shop. If you want to submit it faster though, you can do it manually by clicking "Bulk-edit variants for Meta" (as shown below) and resubmitting the spreadsheet.
For making mass edits to address errors, a bulk upload spreadsheet is a good option depending on the error.
