I have a non-X1 system, and the TV Remote app is rather poor for it. In particular, the DVR-related section for Recordings and Scheduled recordings. They have always been a bit flakey, but have become really useless. The Recordings is mostly working, although it has the normal lag of 12-24 hours. The Scheduled recordings entry has not worked since March 9. No big deal, but if you don't plan on supporting non-X1 properly, then just disable the feature.
