Hi and thank you for your suggestions.
All of the above are already correctly detailed as you have described. Note: under 'Advanced' within 'Media Network' options only "Customise Views for Gizmo and WebGizmo are shown and NOT JRemote. not sure if this is an issue.
As per my initial post and attached screenshots. The only view showing in the app is Theatre View. Upon swiping left the JRiver logo is displayed on a black backgound. the play, Stop, next track buttons at the bottom activate their functions but totally blind!!
Gizmo, my previous used app is fully functional showing ALL library views. JRemote app is performing the same on multiple devices?
