I have been having the same problem since yesterday, 11/16. It was only my Roku tv is my bedroom not working yesterday, and the only work around I found was to restart my internet modem. I came home today and now my living room Roku TV updated and would not work and the bedroom tv wasn't working again. So again I restarted the modem and was able to watch my Sling TV app. I will NOT restart my modem every single day just to get this to work. I will find another way to watch live tv and my other apps that I pay for monthly. This should be a top priority fix since I am seeing that I am not the only one having this issue and seems to be widespread with this new update.
Thank you for working this. I have similar issues as other posts. Good internet but apps say there is not a good internet connection. Netflix, F1 channel, and SiriusXM work. Prime, Apple, HBO, and Disney allow me to log into app but unable to stream.
Netflix kiiiiinda works............but nothing else works. SlingTV loads, eventually, but wont play anything. Discoveryplus gives me some DRM protected content error message, HBO Max doesn't load at all. Frustrating.
