Touching the footswitch once advances the song as normal. Further touches do not advance the song, but open the song folder instead.
Prior to updating the firmware, the song advance worked perfectly.
After updating the firmware, I immediately went to the footswitch settings to set switch 1’s “stopped” behavior to Song Back and switch 2’s “stopped” behavior to Song Advance.
Testing it yielded the above behavior.
I restored the footswitch settings to what they had been before the upgrade: 1 - Accent Hit, 2 - Song Advance. Behavior continued as above.
I disconnected the BeatBuddy, waited a few seconds, plugged it back in, and tried again. Behavior continued as above.
I can provide a video of the behavior if needed.
