I have the Amazon Sales Channel installed on Magento 2.2.9 .
I have 4 products in the "Ready to List" tab.
When I try to publish them to Amazon I get the following error message:
Failed to schedule the listings to be listed. Listings must be in a "Ready To List" status. Please try again.
I have tried publishing one or four but I get the same error.
How should I troubleshoot this error?
