Haven't seen the issue on the web, but I'll charge my MX Keys for Mac for 4+ hrs then it "dies" seemingly randomly. It'll also not respond to certain commands or inputs. For example: the brightness up and down shows the scale when I have this app open but the brightness remains the same. And volume seems to only work sometimes with my interface. Should I reinitialize or default or whatever or do I have an internal chip issue? These are certainly not oversights on a $100 keyboard
