Sorry for the delay, From some customer feedback that re-sync the remote and power off the hub could solve the problem, pls kindly try it at first. If still no help, Please download the latest app from google play /app store, then choose the device in app, edit in device mode, Edit---Add / repair keys----(Vol +) repair---command repeats, change the number to 1 or 2, and try again if the function is OK. You can apply modifications to all commands

If the app button is grayed out, it may be that the hub is currently doing something else (such as upgrading, etc.), please manually exit the app and click on it again after a few seconds to see if it works. If not, you can try to unplug the hub, without re-pairing, and directly click on the shield device to see if you can control it.
