I updated to 4.184 and the 'Turn Stream Deck On' function no longer turns the Stream Deck on. 'Turn Stream Deck Off' still works correctly. As does the brightness control.
Running Mac OS version 13.4.
I've been using this as part of an automation since Stream Deck control was first made available. It would be great if this was fixed. Restarting Better Touch Tool or unplugging the USB is the only way to turn it back on.
