D400 remote app “connects” on iPad and iPhone but won’t actually adjust anything?

I have almost the same problem with my android app. I can change source but not volume with the app when the source is usb. With phono the volume works.

Thanks frejo , at least you can change the source , mine is totally non functional but pretends to work. Did yours just stop working or did you change some settings? I’ve unplugged the dev, checked the wifi settings and deleted the app several times but still no luck...
