I have a tv from them and one day the PBS kids app just stopped working. I contacted customer support and they just told me it was the app developer’s fault, nothing to be done. Waited months thinking it would eventually resolve but never did.
And recently where they:
Blocked people from using their tvs until they accepted a new agreement and
Filed for a patent that defines how they can start overlaying ads on top of other connected devices over hdmi
Glad I shut off wifi to my tv years ago and plugged in a separate smart tv hdmi dongle. And not getting anywhere near anything that says Roku on the packaging again.
