I have lg c7 - playbase - shield tv - (trying to fully) control with harmony companion remote.



All set up working with the remote, however, after a few minutes i can no longer adjust the tv volume with the harmony remote, the volume overlay appears but does nothing.



If i then grab the lg 'magic' remote, volume works and also works on the harmomy remote but again, after a few mins i cant control volume with the harmony remote.



Any solutions? Ive added the playbase to the harmony but cant assign playbase volume control to the shield tv activity.
