Hey everyone!

Sorry to hear about the issues with the Sling TV app! If you haven't already, I recommend trying a few troubleshooting steps to see if we can get this issue sorted:

• First, navigate to My games & apps from the Home screen.
• From the apps tab, select the Sling TV app.
• Press the menu button on your Xbox One controller.
• Select Manage app and press the menu button.
• Select Uninstall.
• Once the Sling TV app has uninstalled, press and hold the power button on your Xbox One console for 10 seconds.
  
• Unplug the power cord to your Xbox One console and unplug the power cord to your router, modem or gateway.
  
• Wait 5 minutes and the plug in your console, router, modem or gateway.
• Power on your console and navigate to My games & apps from the Home screen.
• Scroll to the right and select the Sling TV app under the Ready to install section.
  
• Select Install and once the app has installed, check to see if you are running into the same issue.
  

Give the suggested steps a try and if the issue continues to occur, I recommend reaching out to Sling TV for further assistance. You can reach Sling TV from their Contact Us page.
Feel free to post back letting us know how everything went. Thanks!

Chum, I've been using the Sling TV app on my Xbox One for 2+ months now...

Yep. I'm having the same problem. Sling TV is working fine on my Roku which is hooked up via wifi. But it's crashing and freezing on the xb1, which is hooked up via Ethernet cable. It's not my connection and it's not Sling TV. It's either the app or the
xb1 that's the problem. I tried reinstalling the app and no difference. Netflix and other streaming services work fine.

it works better on PC. I bought an Amazon Fire TV and plugged it into my Xbox One and the app for Amazon works 100% better. You can also use the Watch ESPN app through the Fire TV once you have a Sling account.
