Thanks! I saw the icon there on 2 drives (it was my first time using FSD and it was impressive) but it was again gone on the 3rd drive. I was out of the car for a bit and when I got back the button wasn't there anymore. I tried putting it in park, tried different destinations, I tried it again on a bigger street (all streets had road markings). It just gives me the option to end navigation, without showing the yoke button next to "exit".
Is this common? That the option just goes away sometimes? (Not even grayed out, just not there at all.)
