What happened to the log off in the upper right hand gear symbol ??

Good Morning, @humdmd. 

The reason why you're not able to log out from the gear icon anymore is that we've updated QuickBooks, and it's moved to a new location within the product. No worries. It only takes a few simple steps to get there. Here's how: 

1. Open QuickBooks. 
2. Go to the top right-hand corner of the home/dashboard page and press the new icon to the right of the Gear (Settings) button. Note: The icon will look like a circle with a letter in the middle. 

       3. From here, you can tap Sign out. 

It's that easy! For future reference, here's an additional link that can provide helpful information for your business: Managing users. 

Let me know if this helps. I want to make sure you're able to log out of QuickBooks successfully. Have a splendid day!
