Wait, do you have to have an address in and then go to the menus where autopilot is and then flip a button on each time you want the FSD Beta to be active? Wow, Tesla needs some instructions with this...I had the same issue, got the update yesterday and had no option to turn it on in the autopilot tab. Put an address into the navigation and then you should see the option to use full self driving in the autopilot tab.
Also, still can't view my sentry live cameras... I've got the option turned on in the car and my app is the latest update, but it just times out while trying to load the camera feed...
