My APP check update by comparing local version and remote version returned by iTunes lookup API. But the API still return old version after new version has released.
https://itunes.apple.com/us/lookup?bundleId=com.xxx.xxxx
This API return new version(4.9) if I request through browser, but return old version(4.8.1) in APP.
Anybody help? Thanks.
