Welcome to the Community, msie814446.

You can edit customer profiles by clicking your Edit customer info option while editing an invoice.

I tested this out myself in our test drive account and noticed nothing happened after I selected the link.

Here's an image showing my experience:
 

After noticing this, I reviewed our ongoing/solved investigations to see if there's any reports of this occurring for other users. I can confirm there's currently an ongoing investigation into this issue that began yesterday.

If you'd like to, you can get in touch with our Customer Care team and reference the investigation's case number (INV-95281). They'll be able to pull it up and add your account to our list of affected users. This assures you'll receive email notifications about any updates relating to our investigation.

They can be reached while you're signed in.

Here's how:
 

1. Use the Help (?) icon.
2. Click Contact Us.
3. Enter a description of your situation in the What can we help you with? text box.
4. Hit Continue.
5. Select Chat with us or Have us call you.
   
   

Be sure to review their support hours so you'll know when agents are available.

If there's any questions, I'm just a post away. Have a wonderful weekend!
