Content libraries and playback rights are separate checks
The same platform may show different libraries in different countries or regions. After connecting to a route in the target region, the platform will usually adjust its home-page content based on the exit IP. When playback starts, it may check the account status, title rights and device environment again. In other words, seeing a title and being able to play it are not always the same thing.
If the page has switched to the target region but playback still shows a regional message, first check whether the account itself meets that region’s access requirements. Then check browser cache, app cache and route type. Repeatedly switching between regions makes diagnosis harder, so keep one target region and one route fixed while troubleshooting.
