If you are on US smart hub and netflix app won’t start. This is not Trickbyte dns issue. You can confirm it by switching to public dns like 8.8.8.8 and 8.8.4.4
Here how to fix
1. Change smart hub country to Non-netflix country. Try Japan, Thailand, China, etc.
2. After it, change smart hub country to UK
3. Try open Netflix again.
4. If you got it works, turn off auto update.
5. Change smart hub back to US, if necessary.
Please note, we can’t guarantee how long will this method work, it depends on Samsung to fix it.
