Screen goes black with progress circle every 5 minutes or so.
TV screen periodically goes black with rotating circle in the center and lasts for 3 to 5 seconds. Over the course of an hour it will happen 4 or 5 times.This started happening recently. I am streaming through the app on a Samsung TV. I have Verizon Fios fiber internet running over 900 Mbps. Any ideas what might be causing this?
