I have a new Ruko Ultra 4800x software version 11.0.0 build 4193-C2. wired network Good (93 MBPS) all other channels load fine. Expect You Tube. (You Tube version 2.22 build 105005058) I tried removing the channel restarting Ruko before reinstalling the you tube channel. Checked for updates for both but no luck.
It shows the you tube logo for two seconds then directly to a black screen. Nothing else until I hit the home button. I checked for updates. Restarted via software. Tried leaving the Ruko unplugged over night and reinstalled the channel the following day with the same results
