Hey, @meghannchannell. 

It's great to see you back on this platform. I appreciate you coming to the Community with your question about your PNC bank not connecting. 

Before digging deeper, are you receiving an error message after clicking the Update button? This will help me determine the root of the problem and give you the best solution for your business. 

In the meantime, you can review this link about what to do if you get a bank error. 

I'll be around shortly to look over your answer and respond back to you!
