I have Roku TV and have been trying to access apps. I have a Uverse package and I cannot access all the apps I should be able to. Some work well, some don't. The error I get is about a problem with authorization. I have cleared cache, deleted and reinstalled the apps, all to no avail. I have contacted some of the channels involved and when I get a response (which is rare), I am told to delete and reinstall the apps. I am tired of paying for cable channels that I can't watch the apps for on roku. Any help?
