Here is a summary of the four major issues that many many SB owners are experiencing since the 2/17 update (well-documented in these forums):
- sleep-crash (crashing while in sleep for a longer period of time)
- hibernate-hello (windows hello not working after coming out of hibernate)
- hibernate-attach/detach (tablet attach/detach not working correctly after coming out of hibernate)
- hibernate-autorotate (tablet screen auto rotate, once tablet detached, not working after coming out of hibernate)
I think item 1 above is the most pressing issue that needs to be addressed by MS, urgently.
Thanks
