I’m experience device freezing on my A4 mkII, which occurs randomly and while in use stand alone. 1.51C is installed, a factory reset has been performed, and a new project create per the general troubleshooting guide. I have opened a support ticket, but I’m interested if the test mode errors provide any insight to anyone in the meantime.
