I bought my model 3 end of Oct 2019 and have had several upgrades to the software since then, and am now current with 2020 4.1.1. I was trying to figure out why up until recently I was able to see "Summon" on my Tesla.app, but now it's gone. I searched various forums and saw conflicting points of view, and by the way I have just the basic Autopilot. So today I visited my local Tesla Service Centre to find the answer, it turns out after a couple of different opinions that the "SUMMON" was only a TRIAL PERIOD (3months as it turns out), but I never knew that, was never told that, and now it's gone am a little disappointed that it is now available as "Smart Summon" if I upgrade for $7000. Wish they kept it as two options, Summon for owners who just want to get it out of tight spaces like a garage for basic Autopilot, and for those that want it to AutoPark etc for the additional cost. To have something and then take it away is annoying, but leaving that aside I love my Model 3.
