My SC2 with the latest firmware release (v 1.4) will randomly just turn off. There is no set time as to how much use time before the problem happens. Happened once after about 2.5 hrs, and once after 41 minutes. There are no audible tones, no normal "Good Bye" prompt. I notice when Carplay on my motorcycle dash shuts off as the headset is gone. I reach for the power on button. the SC2 powers back on, no issues.. everything goes back to working. The shutdown with no notification from the EC2 is a bit concerning. Is this a known issue with the new firmware?
