ITunes Search API returns old data in my APP

Question

My update is APP validation by comparing the local version and the remote version returned by the iTunes search API. But the API is still returning the old version after the release of the new version.

https://itunes.apple.com/us/lookup?bundleId=com.xxx.xxxx

This API returns a new version (4.9) if I request through a browser, but return the old version (4.8.1) to APP.

Anyone help? Thanks.

I have the same problem too. I spoke with another developer, and he came to the conclusion that this could be a CDN problem. (Content Delivery Network)
