The swipe action to open Lunar console is no longer working on builds with Unity 6.
This means that the user can only open the console and debug action if a log is triggered that opens the lower notification bar. Tapping on that opens the full console.
#218 (comment) here is a hint why it may no longer work.
NOTE: unityPlayer.getFrameLayout() worked nicely for me, but it's just a workaround, and in an empty project for some reason it couldn't receive the touch events, maybe because of the structure of the views were unexpected, but you can give it a try in any case.
If needed I can pull more debug data with logcat.
