Lumin Control App

I have a HIFI Rose 250A and currently use a mixture of The Rose App, Mconnect and BubbleUpnp to control my music from a separate NAS unit and streaming from Qobuz. Not an ideal solution as none of the three apps are perfect. I used to use Lumin App on my previous streamer and was simplicity it self, with everything working perfect.
For some reason the Lumin App will not connect to the 250a. Even though it is a DLNA control app. Anybody out there have any suggestions?

I think that Lumin fairly recently updated their App to reduce it’s compatibility with non-Lumin devices.

Thought something along those lines. Shame, Lumin app is a good control point. I now use Jplay app on IOS, which is excellent, 7 days free to evaluate, then a purchase. Controls all sources direct to my streamer, Qobuz, NAS unit and SSD in my HiFi Rose unit. It just works
