Problem to resume between iPhone/ATV/iPad

The main headache with Infuse now that resume sometimes fails,when I watch my movies on different units. Assume this, I play my movie on my AppleTV, stops it, and half an hour later I resume the movie on my iPhone. The resume-position on my phone is not updated.
This doesn’t happen all the time but it’s very frustrating when it does.
I’m using iCloud-syncing. Hints?
