Keep me updated in the comments below. Hope to hear updates from you as soon as possible. Take care and stay safe!

Hi,  I want to add anew customer in the invoice section, I enter the correct email address for the customer but I get the message Invalid email address.  It is the correct address, I use it to email the customer.  I have refreshed everyting, cleared cookies and used a different browser, the same thing keeps happening.

I am adding a new customer so that I can invoice them. Every time  I enter their correct email address it say invalid email address? I have cleared cookies and used a different browser. I am using QBO and I am based in the UK.
