I'll make sure your clients can view their emailed invoices, @ahplumbingandpro.

I've got a few workarounds that we can perform to isolate this issue. I recommend sending a test invoice to your email and check if you're able to view it. If you have, you'll want to resend the invoice to them. 

If they still can't view it, have them open a private or incognito window and access the invoice from there. This way, we can check if this is a browser-related issue.

The browser uses cache and cookies to swiftly load web pages faster. Too much of it causes unusual behaviour. Using a private window helps us verify the issue as this doesn't save any cache files. 

To open an incognito window, please refer to these keyboard shortcuts: 

• Press keys: Ctrl + Shift + N (Google Chrome browser)
• Press keys: Ctrl + Shift + P (Mozilla Firefox & Microsoft Edge browsers)
• Press keys: Command + Shift + N (Safari browser) 

If they're able to open the invoice, have them clear their regular browser's cache to refresh the system. If the issue remains, I recommend using other supported browsers. This way, we can check if this is a browser-integrated issue. 

On the other hand, if you're unable to view the test invoice you've sent to your email, I suggest contacting our support team. This way, they can securely look into your account and investigate this matter.
