I realize some people are experiencing issues with their queues disappearing, or having problems logging on. Netflix is aware of this problem and is working on a fix. I don’t have any other information at this time, but it sounds like all 3rd party Netflix apps are having this issue. Sorry for the inconvenience.
Update (9/3): Talked to someone at Netflix. They said they know about this issue, and are still working on a fix. They didn’t give me a date for this fix.
