I have a Roku Premiere (4620 series) that won’t load any apps. I have restarted my internet, the roku, and have attempted to remove channels and it won’t even do that. Is the machine broken? It said it checked for an update yesterday. I have tried to open Amazon Prime, Disney+, Peacock, Hulu, PBS Kids, and the Roku channel.
The "clear the cache" routine has become my new thing to suggest when all else fails (right after use the supplied power adapter and not your TV's USB port). Using your Roku remote, press Home 5 times, Up once, Rewind (<<) twice, and FF (>>) twice. If you do it correctly your Roku will appear to lock up and then reboot. Be sure to respond to let us know if it worked or not.
