Three issues on my Roku Utra (I have several and they all have the same issues).
1. If you buy a bundle of a TV show on Vudu, more often than not, my Roku decides I have not purchased the content, even if I am trying to play where I just left off. I have to go to the menu and select the specific episode, then it will work again.
2. Sometimes the continue viewing option selects a TV episode that I watched far in the distant past and not the episode I am in the middle of. It is like the Roku fails to update playing data.
3. The new Roku Vudu app is just plain horrible. It is difficult to navigate and frequently does not send you to what you click on. IDK what was wrong with the old app, but whoever designed the new app needs to find a different job.
