Amazon SP-API, Feeds API, JSON_LISTINGS_FEED : PUT Succeeds but Prices Do Not Update

Question

I followed the official documentation: https://developer-docs.amazon.com/sp-api/docs/feeds-api-v2021-06-30-use-case-guide to create and submit a feed using the Feeds API.

The API process itself completes successfully, and no errors are displayed in the Seller Central dashboard.

However, only about half of the submitted updates are reflected, while the rest remain unchanged.

Even after 24 hours, the prices have not updated.

It is possible that there may be an issue with the content of my feed.

If anyone has any information or insights, I would greatly appreciate your assistance.
