Spotify volume control on device not controlling volume on Player/Pi

[gingep]

Hi, new user here.
I had a previous version or rAudio where changing the volume control on my mobile device running spotify would control the volume on my Pi.
This no longer happens and so I have to access rAudio.local to change the playback volume.
Any advice please.

rAudio 20231210
6.1.53-1 armv7l
Raspberry Pi 2B Rev 1.1
BCM2836 • 963 MiB
4 x Cortex-A7 @ 900 MHz
