Break the deal. Get out while you can and look again for a TV with what you want.
I just bought an LG smart TV and am very disappointed to find that it does not have an Amazon app (for my amazon prime streaming videos, etc). I emailed LG and this is the response I got:
"I absolutely understand your concern, and apologize for any inconvenience you may have experienced. Amazon will be supported later on, there is no ETA on when the update is going to be available."
If this "update" ever actually happen, will I be able to ad it to this TV - will the amazon app suddenly appear on my TV's options? Or does this response mean that only future smart TVs will have the update (if it ever happens)?
