Why can't i get my clients e mail address to populate on the new invoice screen i am using, just like it used to before the change over?

Good afternoon, @jamdpm84. 

It's great to see a new face here in the Community! 

Since there's a new invoice screen in QuickBooks Online, I recommend contacting our Customer Support Team. They'll be able to use a screen share tool to review your account with you. Here's how: 

1. Go to the Help icon in the top right-hand corner. 
2. Press the Contact Us button. 
3. Enter your question and tap Let's talk. 
4. Scroll down and choose to Get to callback. 

It's that easy! 

I'm only a post away if you need me. Take care!
