After we'd had out 2016 Model S for a while, it started making us wait "One moment while systems boot up" or some such verbiage. Okay, not convenient but livable. Now, I get in the car and sit there with a black driver's screen, even after the main screen has lit up, and nothing. No "by your leave," it just takes twenty seconds or so before it jumps to life. This is definitely longer and different than before. Is something wrong? Can I expect the wait to get even longer? Is there something here I need to get out ahead of?

Thanks.
