What's the issue?
Not all TV browsers can show our dashboards, play notifications or YouTube videos. We currently recommend TVs running on Android or LG smart TVs with WebOS 5+ (produced in 2020 or later).
Even though we have a native TV app for Samsung TVs, we do not recommend to use it. A known issue is that Samsung TVs are not capable of rendering dashboards well enough, nor can they show some types of notifications like, for example, YouTube videos. It's all because the browser rendering is too slow.
If your TVs have trouble displaying dashboards or notifications, you can consider alternative methods.
