You can use that to return it for a full refund.
You can also post in the usual AVS Forum but no discussion I've seen turns it into a full blown Android with the Play Store and more.
The TV makers want to maintain control and it shows from all makers so far.
If we were to chat over lunch we would go over how the makers cut deals to put the apps on the TV for a cut in the revenue. (A piece of the action.) So when you use Netflix on a smart TV, they get a cut of the rental fee. If they allowed folk the freedom to say use Kodi then no cut.
If you want to break free, add a real Android box but that's in the news too.
