Is it possible to get more than one PIK media box? My smart tv doesn't offer the app so I'm at a loss as how to watch tv on it. My other tv is even older so I have a box for it from years ago when PIK first came out.
No. If you want multiple TV to connect to your account, Optik is the path to follow. Pik is meant for cord cutters, who want limited TV.
NFtoBC is correct - there is a limit of 1 Pik TV box per account. If you want to connect another TV, you can use an Apple TV (4th gen or 4K), Nvidia Shield or connect your laptop/computer with an HDMI. Note that Pik has a limit of 2 concurrent streams; you can connect as many devices or download the app on as many devices as you want, but you'll only be able to watch on 2 devices at the same time.
