I'm trying to use this app Precise Volume 2.0 to get more precise volume control for bluetooth device with very high output volume even on minimum volume setting. However even doing everything as the app instructs and granting the app necessary permissions, trying legacy mode etc. (as per FAQ) I still can't get it to handle the volume button presses when the app is closed: it defaults to the android native volume controls. When the app is open it works as it should with the volume buttons presses.
The only reason left for it not working that I can think of it GOS itself not playing nice with this app. Has anyone else gotten this to work or have any idea what may be the issue? I'm using Pixel 8 Pro.
