Why do these exist? I don't care that some random application has crashed in the background. They don't even make sense. Why is Netflix running and crashing in the background while I'm watching Twitch? Why is the USA Today app running and crashing? Why am I notified of this? I have to find the remote as they don't just fade away. It's completely unnecessary to show this and it's such a poor user experience.
It's because AndroidTV is well, Android, and apps crash, and Android has sent those popups as far back as I can remember. A lot of the apps still run in the background so features like Recommendations or global search can include the items in the app. I had this issue with BloombergTV the most, and just ended up deleting the app.
