Apple TV Issues on Roku Plus
I have an issue with Apple TV.
I purchased 2 Roku Plus for an older LG and older Visio TV last month.
I have same exact issue on both Roku Plus units.
First, Netflix, Amazon, Paramount, Hulu work fine - no issues.
Apple TV has the issue as follows.
If you want to watch a new show (one you have not seen before) there is no problem.
If you want to watch a show/movie again the Apple TV starts then the spinner icon pops up and the show stops.  Eventually it asks you if it wants to trouble shoot the issue and if you say yes, it runs its review before telling you that it cannot fix the problem and to try again.  This issue also pops up if you are watching a series and you want to pick up the series 1/2 way through an episode.  Again, this issue does NOT happen if you have never watched the show, only on shows/movies you have already started.
We have done all the advised steps from Roku advice.
1. kill app, restart Roku, reinstall app
2. Amend sound to stereo
3. hard reboot Roku by unplugging
4. Reboot router
Have tested the wireless speed at both Roku sites and it is 320 Mbps download/620Mbps upload speeds.
So frustrated. 
The whole reason we got the Roku sticks was that we got tired of connecting laptops to TV everytime we wanted to watch a show/movie.
What is the solution?
Help.  PLEASE.
Thank you.
