In general, I’d appreciate recommendations for it, but a third party youtube app would be great.
I just installed jellyfin via a one line docker install which worked great.
Edit: Tizen OS is horrible. The whole OS is one huge ad.
The settings are spread across everywhere.
It has multiple different views for apps and recommendations and movies. Everything is mixed together into one giant swamp in one view.
It runs Android TV, so you just need to get the APK onto your TV. You can download a file manager from the Play store (I use X-Plore) and use that to install the APK from via USB. Alternatively, you could download a web browser from the Play store (I use TV Bro) and download the APK directly on the TV.
