Helix Floor:
 
	I recommend to do a factory reset after updating to 2.81 in any case!!
 
	a month after the update I realized this: switching back from Snapshots to Manual Mode with the Cancel button does not work anymore!
 
	Made a global reset(of course with a backup) - works fine again now!
 
	did not make the reset after the update... which was a big mistake!!
