I have an AMEX High-Yield Savings linked with my AMEX Business account. I can't add it to Quickbooks. All my other accounts appear on the list except the HYSA.

Good morning, @Safco. 

It's great to see you back in the Community! 

I recommend contacting our Customer Support Team so they can review the back end of your account. 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 a callback. 

It's that easy! 

Keep us updated on how the call goes. I'll be waiting for your response!
