Good morning ! Several times after using my Polybrute without issue, the screen froze. All the buttons seem to work but the screen is stuck on displaying the last preset I used. So I don't see what I'm doing anymore. I specify to use the last firmware 2.0. I turn off the Polybrute, turn it back on, everything is fine for a while and then all of a sudden the Problem comes back. Screen stuck while everything seems to be working fine. Does anyone have the solution? If you want you can reply in french.
