Have had 2 roku sticks update to version 11.5 tonight of Roku OS. After the update spectrum app will not do anything other than play default channel. Trying to change channels, go back, bring up the guide, do anything results in a spinning wheel that never responds. Can only go back home.
Update - After allowing some time after the update install, all devices eventually did load up a EULA page in the app. After agreeing to the EULA again the spectrum app started working correctly.
Thank you for reporting back. I wish more people would do this.
