Many people are saying about how wobbly the touch id is but I heard no one mention that you can actually press the Touch ID like a button. Is everyone's macbook like that? Is it an actual button or a manufacturing issue?
Yes, the Touch ID button doubles as the physical power button. You can press it down to turn the computer on/off just like you could with the power button on previous models.
If you don't have a finger print sensor notification after opening up the computer, you probably haven't setup a finger print yet. Go to System Preferences and Touch ID to set it up.
I suppose I should also mention that on my previous late-2016 15" MBP that power button was extremely wobbly. I replaced that machine with a 13" tMBP and the power button isn't wobbly at all. So it's definitely not an issue with all machines.
Yep, I had a Finder freeze and had to go onto my iPhone to search out how the heck to force the MBP to shut down. Can confirm... Touch ID button moves down when pressed and acts like power button.
