TopShelf refresh question

All,


A customer of ours wants to fill the top shelf of their tvOS app with a list of 3 items that are currently playing. We've implemented the software, but notice that the top shelf doesn't refresh all that often.


So you end up in a situation where the items that currently playing (according to the tv guide) differ from the items that the top shelf loaded earlier.


Is there a mechanism to refresh the top shelf?


Many thanks in advance.
