Re family sharing, 6 people could be on 3 devices under your account. Go into the tools section (Circle w your initial in upper right) while in the app. Click on settings then membership and family sharing. You can invite 5 people. You and they have to be set up on google family. Worth taking 10 minutes to figure out. You can chat w them if you need help. My tech challenged SIL had trouble, but the kids were set up and using it in minutes.I wanted the local channels on my TV, so I went with the Roku. I got the Rohu Ultra. It also had some other features that I liked, and its a one-time purchase, so I got one.
Tell me more about the family stuff - I knew I could add more people, but thought I was limited to 3 devices at the same time, even with more accounts. No?
