Same here except on PC. 
 
	Can't engage Nav or managed Modes (Alt or Speed) when I made manual changes prior. 
 
	The Buttons do click in but doesn't trigger the managed modes. 
 
	Also I noticed for a DIR I have to go back to the FPL page and activate a temporary change for the DIR to happen. But then I have the above mentioned problem. 
 
	Love the plane so far especially the EFB and Takeoff Calculator.
 
	 
 
	Thanks for the great Work
