I just installed the Roku 4K Stick on my Sony TV. I started adding apps and signing in. All of a sudden, when I clicked on any app, nothing happened. I looked at the support page, re-signed to my network, and checked the connection, and everything was fine. I clicked on some. more apps, and everything was opening and doing fine, but then, all of a sudden, I couldn't open any of the apps. I checked my network connection, and it said everything was fine, but I still couldn't get the apps to open. I turned off the TV and will try again later. What is going on?
