Since updating the newest version, the Master button not lighting up and the audio icon at the top center ofthe screen is orange. Any idea whjat caused this change?
Yeah, it's a known bug. Of which 3.11 has quite a few. You can start the old version of traktor from the backup dir.
You can also find the post from @Stevan where he has a mapping that reverts some of the bugs s4 bugs.
Thank you!
