In invoice, when I click on the options drop down to preview or email, the connection icon spins and the invoice does not appear?

Hi there, 

I know how important it is to preview and email your invoices in QuickBooks Online. Making sure your invoice looks just how you want it and then being able to send it directly to your customer is going to save you tons of time. I'd be happy to walk you through some troubleshooting steps if you're having issues with a spinning icon.

Try clearing the cache and cookies in your web browser to remove any stored Internet files. These stored files can cause bugs in QBO and other sites. Here's how to clear them: Clear cache and cookies to fix issues when using QuickBooks Online. 

If the issue persists, try using an Incognito window in Google Chrome. This is a private browsing mode that operates separately from the main browser, and it doesn't get impacted by stored cache and cookies. Here's more information about that and how to use it: Browse in Private. You should also try using multiple different browsers.

If you're still running into issues, I'd recommend touching base with our tech support team so an agent can take a closer look at what may be happening. I'm confident our team will be able to sort this out for you.

Cheers!
