If I assign some things to the footswitch, save the pedal board, then disconnect and reconnect the footswitch, those assignments are immediately lost! This is a serious inconvenience - basically it means that I cannot use the footswitch on a gig unless I bring my laptop along with me so that I can reassign functions to the footswitch after connecting it. So for me this is the #1 most significant bug with the footswitch right now.
I’m guessing this is also the case with MIDI learns? If so, it’s an even bigger problem.
I thought I had seen this reported elsewhere, but if so I can’t find it :-/ I even have a vague memory of expecting it to be fixed in an upcoming release, but it’s possible I imagined that.
