Why am I unable to send out invoices for the past 2 weeks? I keep getting delivery error message

I can help you send your customer invoices, @firstclassdetail.

Before diving in, may I know the specific error you receive? Any information can help us determine the cause of the issue.

In the meantime, let's perform some browser troubleshooting steps. Let's start by accessing QuickBooks (QBO) account using a private browser. The following are the shortcut keys you can use:

• Google Chrome: press Ctrl + Shift + N 
• Mozilla Firefox and Microsoft Edge: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If this works, you can clear the cache and cookies of your browser. If not, you can use another supported browser. Possible that your current browser may have a temporary issue with QuickBooks.

Let me also attach this article that you can read for future reference: Customize invoices, estimates, and sales receipts in QuickBooks Online. This includes the steps to add details to your invoice.

If you have any other follow-up questions, let me know by commenting below. I'm here for you. Have a great day!

I use the Quickbooks Online app on Android. I have been using it for 6 years or so without problems. These past few weeks, it has not worked. I have already spoke to employees and they told me it is a known bug, which was supposed to be fixed by now. The issue is not on my end. 

Thanks for joining us here, @firstclassdetail.

Let's get your QuickBooks Online app working. You'll want to reset your data. This way, the app will refresh its connection and sync with the updates. Here's how.

For Android device:

1. Go to Home.
2. Tap the Hamburger icon or the three dots.
3. Select Settings.
4. Click Refresh Data.
5. Select Yes when prompted.

For iOs:

1. Go to Help.
2. Select Reset App Data.
3. Click OK.

Next, reload the app again to see if it's now up and running. Tip: You may need to reset the app multiple times to update properly.

None of this helps. Like I said, I've been using this app everytime I send invoices for the past 6 years. There is a bug in your system.  I have Uninstaller the app several times. Nothing works. I have even used Google Chrome.
