Hardware Button on IPhone

[Trailscout]

For some time now, I have not been able to adjust the volume of my Wiim Pro using the volume buttons on my iPhone. Do you have any ideas? I obviously haven't changed any settings. Thanks

You need the WiiM Home App to be open in the foreground (and you must not be in the device or app settings) to be able to control the volume from the volume buttons.

Yes shame it's not like the blutooth output where the phone does not have to be open
