I have an X1 remote that I just started using 3 days ago. Everything has been working great until today. I went to start an Activity from the X1 remote and nothing happened, the remote would show it was trying to start the activity but nothing would actually start. I went in and did a sync from the remote and it stuck at 0% indefinitely. I decided to launch the Activity from the iOS app and that worked fine. Once the Activity launched from the app I noticed the remote started to sync. Not sure what happened. Hopefully this was just a fluke. Will report back if it happens again.
