John:
This started with the most recent update to OS14. There are two issues.
1) My Rokus randomly reboot and restart. This has occurred on more than one of my devices. I have 5 Ultras. I have currently followed the advice of customer support and unplugged power for 30 seconds to see if that fixes anything. Since it is random, I am waiting over the course of this week to see if there are any reboots. So far, in the last 2 days, this has not happened.
2) This is with the Spectrum TV app. This also started occurring since the last OS update to 14. When I initially attempt to open the Spectrum TV app on the Rokus, it starts to open the Spectrum app, but then goes to the Roku Home screen. On the second attempt at opening the Spectrum app, the app works as normal. Again, only started doing this after OS14 update. I have not noticed this issue with other apps yet.
To answer your questions. My primary Roku is hardwired into the router. The 3 of the other 4 Rokus are wi-fi in various locations of my home. The other is hardwired into an Orbi satellite. There has been no network change, and I don't believe that the network is responsible this issue.
This is strictly a Roku firmware/app issue because the Roku functions normally after the reboot of the device until it randomly reboots hours or days later (again still waiting to see if the unplugging of power fixes that issue) and the Spectrum app functions normally after opening a second time as it only does this on initial opening of the Spectrum app after turning on the TV and Roku device.
Thanks
