Force sync to Videos app for recent purchases?

I've been purchasing movies on iTunes for quite a while, and I've had the same issue on my iPad Air 1 for months. When I buy a new video on the Store, it doesn't appear in Videos for at least a day. This is, needless to say, rather annoying.

Things I've tried so far:

• Restarting the app (double tap home, and swipe the app up)
  
  
  
  • Both the store and the videos app.
  
  
  
  


• Restarting the iPad.


• Swiping down to try to "refresh" the list.


• Signing out of the iTunes store and signing back in.
  
  
  
  
  • This one actually works... For a minute...
  
  
  • Must do this every time I buy a new movie, or wait a day or two.
  
  
  
  

Any suggestions for clearing the Videos App's cache? Forcing a sync, etc?
