First off i have...

rebooted the router

Done a restart/reboot on the appleTv

Tried different profiles

None of which have made a difference

So the problem is that some tv shows and episodes just will not play, whereas others play just fine

examples are

Last kids on earth s3 ep10, just sits with the round waiting circle

Bureau of Magical thingies, just sits with the round waiting circle

I tested last kids on earth on my phone and it ran perfectly, is there something I am missing, I don't particularly want to do a reinstall of the app, but i am guessing thats the next step?
