Unfortunately, after running Mac OS 11.2.2 the "DISK NOT EJECTED PROPERLY" message is back as my LaCie 2Big Dock is dismounting on it's own again.

AHGG....
 
Disappointed to report that macOS 11.3 once again breaks waking my LG 4K monitor connected via USB-C. Grrr. Feedback submitted, waiting begins.
 
I am excited to report that 11.3 appears to have fixed my sleep/wake and system crash issues with my LG 4K 32UL950 and M1 16GB/256GB. I had to initially change the monitor DisplayPort setting from 1.4 to 1.2 in order to have a somewhat stable system. After the update was completed last night I set the monitor back to 1.4 and have been testing the system and it’s all good SO far. I am running USB-C/TB to USB-C/TB.
