That is like asking, "Why isn't Google Play in Windows store???"

When they offer it

I think it has to be updated from the firmware update. Which can done in the Network Settings of a Hisense TV

Hello.

I got a Hisense H5B series.

Every time I enter the Opera TV Store it goes to the terms and conditions scree, in which I accept.

I app and application, then return and it is not to be found in the main menu.

Can this TV not install new apps?

Nothing
