I have a Roku 4620 (Premier) which worked as expected for over a year. Currently though I've been plagued by restarts - several each day. The restarts occur at relatively random times and across different apps.
What I recently discovered was that the if I check the System/System Update log after a restart, I'll see an entry for checking updates with a time stamp that matches the restart time.
This has been consistent for the last few days. Anyone have any insight to this or similar experience?
