Naim app in UPNP

I’ve recently updated the firmware on my 2015 Uniti 2 to V4.9. This has enabled me to regain access to internet radio again (thanks Ross at Naim HQ support). However I have a problem when playing an album from my QNAP NAS. If I use the Naim remote and scroll to an album the tracks are presented and play in the correct order. When I use the Focal and Naim app on my iPhone the album is presented with the tracks in alphabetical order meaning that the ‘story’ becomes lost and the tracks are not played in the order which was intended. Has anybody experienced the same issue and/or managed to overcome this?

The UPnP server provides the Naim app with the track order. What server software is it?

You haven’t enabled shuffle by any chance on the Naim app?
