Since recently upgrading to Catalina (all updates applied) the modified Touchbar shows no "volume up" any more, there seems no response to changes in its' own preferences, it's checked within GoldenChaos-BTT. The settings within GoldenChaos-BTT seem not to be reflected in the Touchbar.
I tried removing the preset, and reinstalling from scratch, no dice, reapplying settings… no way.
MBP 15'' German system Catalina 10.15.7
Otherwise, love this! Rolf
