Problems with Hulu app on X1 box

My Hulu app works fine on Roku and on my phone - but on the X1 box - not all of the shows in "My Stuff" show up.  I have tried signing out and signing back into Hulu several times, restarting cable box several times - but nothing works.  It's not a horrible problem as I can get to the show by searching for it - but it is annoying.  I chatted with a Hulu rep and he said that it is apparently a known issue but I don't know if it is a Hulu issue or an Xfinity issue.  Anyone else having the same problem?  At this point, after a few months, I guess I'm jus going to have to continue with the work-around or watch Hulu on Roku.  Thanks for any feedback
