That correct. Works perfectly when I launch the app. From Home or any other app it launches the correct channel but does not play.
Just noticed another scenario. If I launch via API from home screen to a channel (e.g. 104) I get the black screen as in the video, then quit back to home, send same command to same channel again (104) and it plays, I can then send a command to switch to any other channel and it works.
If I press the back button from the app, regardless of how I launch it it will just keep taking historical steps back, e.g. back press = change to last channel, back press = change to channel before that, back press = Go to guide and so on. Only way I can quit the app is by pressing Home.
I'm running the beta for scheduling, haven't tested any of this on the current public release. Version is 1.0.24-beta.
