Smart summon hasn't worked normally for me for months
The only way I can get it to work is to use regular summon to move the car a little
Then smart summon will connect
I don't have smart summon standby enabled, since I hardly use smart summon.
I usually only try it when there is a new software update to see if there are any improvements
and to see if it will work without using regular summon first
