I have touchbar buttons to launch applications that show up when I press the option key. ('launch application' predefined action)
When I switch applications using these buttons it always shows the default touchbar behavior and ignores my preference to 'show bettertouchtool touch bar'.
When I use command tab to switch applications the preference to show the bettertouchbar touch bar works fine.
This also happens when I use the app switcher widget.
