Thanks for getting back to us, @userlee1.

I appreciate your efforts in performing the workaround provided by my colleague above. I also certainly understand the convenience of viewing an attachment from the entries easily. 

Since you’re still experiencing attachment issues, I’ll help in pointing you to the right support so we can get this fix. It’d be best if you reach out to them so they can further check for any ongoing or known issues.

Here’s how:

1. Go to the Help icon.
2. Select the Search tab and click Contact Us.
3. Enter a brief description of your concern.
4. Hit Continue.

Here’s an article you can read adding attachments to customer and vendor profiles, as well as their transactions: Add or delete attachments in QuickBooks Online.

If you need help with navigating the program, refer to this website for tips and other resources for reference: QuickBooks Help articles. This will help you manage your income, expenses, banking, inventory, and reports.

This thread is still open if you have further concerns with attachments or any other questions about your QuickBooks Online account. Rest assured that I'm all ears and ready to help you out.
