I guess I’m not alone... as others have experienced my #1 button has stopped working completely... just submitted a support ticket.
Seemed to have started with the update to 7.1.3.15295, however it may be coincidental. The button feels ok, just doesn’t do anything when pressed. Started slowly, only not working every now and then as well as also coinciding with the “date/time loss” - strangely enough... that issue corrected itself so I was hoping this would as well. I guess not.
Sad - LOVING the sounds I’m getting and even after only having less than three weeks I’m very at home with it. That unit is so easy to program ... just about any tone I have in my head seems to be possible. Not sure what will be the outcome - but I did a backup in case on my flash drive in case I have to return it.
