I have tried to use summon several times but sometimes it works and sometimes it doesn't. The problem occurs on my phone. When I open the Tesla app as often as not I get a message about updating, yesterday, an hour ago or some other time in a banner at the screen's bottom. At this point I cannot connect to the car but when I get into it and drive sometime later I can connect to the car and summon works. So, sometimes it works and sometimes it does not. I am generally standing in sight of the car and it is no more that a hundred feet or so away with a clear shot to me.
I'm stumped.
