jjetset,
"When you go in to the app it says your most recent channel is playing track Z, track Z is two tracks away." The app seems to be showing the current "live" track. If you use the GoLive feature, it appears to be correct.
"When showing the thin light blue track progress bar (assuming it is track progress) never seems to move off of 3/4 complete so is completely broken." Mine was at 1/3 this morning, but you're right that it doesn't move. The "progress bar" also shows the start of the hour on the left and the end of the hour on the right, neither of which is correct (unless they're displaying GMT??).
"If you ignore most recent stations and instead go into favorites and then select the radio station it seems to play for much longer in my recent experience." That was not my experience. It was always approximately 20 minutes regardless of how I started a station playing. Even worse, on Sunday I couldn't get any more than 5 minutes before freezing. No matter how I accessed and no matter which station. Then on Monday it was back to the 20 minutes.
It looks like SXM is attempting to create a similar UI across platforms, because the "new" Roku version bears a more striking similarity to the Android phone and AndroidTV versions of the app (which, in my opinion were inferior to the original Roku version), but there is no doubt that the upgraded Roku version was prematurely released.
