I even sent an email to panasonic and never heard back.
That's the problem with all of this "Smart TV" technology. They don't keep up with it after the initial sale and you're stuck with dinosaur versions of apps.
My best advice is to find your nearest authorized Panasonic service center, and get a repair estimate. After a few days of bitching at Panasonic, I got them to cover $~160 of a $410 repair job. Less chance of screwing it up yourself, and you get at least a 90 day warranty on the service and parts from the shop most likely.
This and the lack of HBO GO app are the most disappointing things about this TV for me. Pretty inexcusable
