Suddenly my Roku 3 is rebooting almost every day and is not functioning for many channels; it will not play Fox News at all, it simply goes back to Home setting; You Tube is loading slowly, and other such issues. This all just began in the last week. It is not my connection, I have 5G with Spectrum. I rebooted the modem. My smart TV works fine, it isn't my connection. Do I need to purchase a new Roku? Is there some reason you know of that caused this problem recently? TY.
