Re: HBO Go, Roku and Cox Yes, anytime I activate the 3rd device the other two get disconnected. I wonder if there's a limit of 2. I've never owned more than 3 Rokus. In fact they're still the original streaming sticks; I've never upgraded them because they work just fine. I don't have any additional Cox usernames nor have I ever given out account information to anyone. I take care of everything so the household just has to fire up the Roku and start streaming. I don't own a smart phone (nor does anyone in the house) so I can't test your phone app theory. And, yes, having an authorized devices list in my online Cox account settings would be grand. We're a household of seniors and we don't go out much except for doctor appointments and grocery shopping so TV is our major entertainment. Re: HBO Go, Roku and Cox There is no password for HBO Go, when you sign in it takes you right to the Cox login for authentication (my one and only account I have-admin) and I change that password regularly. Also not using a sub-account. I did contact HBO Go and Roku first and they both responded that login issues are tied to Cox which is why I posted my question here. HBO Go, Roku and Cox I have 3 Rokus in my house and HBO Go is installed on all 3 of them. Starting with the recent "new" app upgrade I've ran into an issue. If I activate only 2 of them there's no problem but if I activate the 3rd one the first two get logged out. Then if I reactivate the 1st two the 3rd one gets logged out. And I'm not talking simultaneous streams, I'm talking just being logged in to see the watch list, etc. I don't have this issue with any other providers so is Cox limiting how many devices can be used?
