I Have run the new update available yesterday there was none.
Anyway it has been updated and is now working
I had the same issue, I had it search for updates and tested it then they worked.
However, now every time I turn off my tv,my Roku turns on. Not good.
Obviously I am not alone here. Prime and Netflix started to crash about 3 weeks ago and nothing seems to correct it. Judging from all the requests this is not an individual device issue but a systemic issue. Do not put the onus on the end user.
Roku - JUST FIX IT! before I purchase a Fire Stick.
