See, for me, having to stop typing on my laptop and reach over and unlock the phone using Touch ID was inconvenient. It's much easier to unlock with Face ID. I don't have to remove gloves when working outside, I don't have to make sure my fingers are clean (I work on construction sites, and this often blocked Touch ID from working), etc.
What's inconvenient for me is NOT Face ID...but the insistence on Apple's part that even after unlocking with Face ID I still HAVE TO SWIPE UP TO START USING THE PHONE!!! I find that stupid, I get why they did it, but I think that should be a totally optional thing that's selectable in settings. It annoys the crap out of me and I blame it mostly on the Touch ID system. Apple things we want to fondle our phones. I personally do not.
Don’t wait to swipe. Just do it before or at the same time. I expect in a future software update they may give you the option to unlock immediately. I personally like it this way as I can see my notifications once it recognizes my face. Like a secret spy phone
