Every customer tells me they can't view their invoice. I've just tested it myself from my phone and get the message that Outlook is unable to download. Has anyone experienced this?

I appreciate the complete details you've shared, @prettystitches-l.

Once your customers received their invoices, they'd initially see the total invoice amount. They have to click on the Review and Pay button to see the complete invoice details. I've shared a screenshot for your visual reference.

They'd be routed to a new tab where they'll see the option to view, download, and print their invoice. This way, the invoice will be downloaded in a PDF format. There will be an invoice pop-up once they've clicked on it.

Also, you can let them try viewing the invoice on a private or an incognito browser. This way we can isolate the prompt for a possible browser-related. Here are the shortcut keys you can use:

• Google Chrome, press CTRL  + Shift + N
• Mozilla Firefox: press CTRL  + Shift + P
• Microsoft Edge: Press CTRL  + Shift + P
• Safari: press Command + Shift + N

If they're able to successfully view their invoice, you'd want to let them clear the cache of their regular web browser. Also, you can use let them use other supported browsers.

If the issue persist, I'd recommend contacting our Customer Care Team. Please take note of their hours of operation so you know when they're available.
