It's interesting you get an error message when the NBC News app glitches on the Roku TV. Using the #Roku 3 (4200 series) I find this app frequently crashes the device, causing it to reboot. And I get no error message displaying. I have now purchased the Roku Ultra (4800 series) and have had the app crash out to the Roku Home screen (but not cause the device to reboot) a few times within the first couple of hours of operation.
Since I've not experienced these problems using the Amazon FireTV stick, I conclude there's a problem with the most recent couple of builds of Roku's NBC News application. I honestly don't know how to report these problems to the developers of that app. I've used the app's feedback function, more than once and posted to similar threads here on Roku's Community forum. At this point, however, I feel as though I'm just shouting into the wind.
