Amazon Prime add-on - images not showing during navigation

Hi,
I just upgraded to OSMC on raspberry pi B+
I tried the add-on Amazon Prime (installed form zip) - seem to install and enabled ok.
The app load and seem to run ok but during menu navigation I do not get images/thumbnails displayed.

  • just seem to show default ICON symbols

Is there a setting or something that needs to be enabled?
I tuned on debugging and no errors show in the logs during navigation

Thanks

Need windows since Amazon and Showbox are DRM protected

there is a way to use those services although not native
