Just wanted to share with you what helped my UI work better. Seems obvious now but at first my UI on my pc was really slow, the pedalboards took ages to load up and multiple disconnections happened.
Also the banks interface was faulty.
I just deleted all the pedalboards that I really did not use. Maybe 15 boards or so. That seemed to lighten to work rate. Now it runs much better.
So if you are experiencing a slow UI, try decluttering and getting rid of stuff you do not use. Seemed to work for me.
