I had a Roku 4K+ that was working fine. About 2 weeks ago I had to start to press the restart button every time that I wanted to access Roku. I thought the unit was defective so I bought a new Roku ultra. After I got the new unit up and running I am still having the same issue. I am assuming that it has something to do with the update. How do I correct the problem?
Look for a new setting for "power saving" under Settings->System->Power and disable it. Even with it enabled all you should have to do is press the Home button on the remote to wake it. If your remote has a Power button that won't do it.
