My email keep comming up with errors when I send invoices from my Android. Can anyone help ?

I can help you with resolving the error you're having to send your invoices from your android successfully, @pergatori666-gma.

Can you tell me more about the error you're having when sending the invoice? That will surely help us provide an accurate solution to the concern you're having. 

You can perform some troubleshooting steps to resolve the error you're having. 

First, make sure to use the latest version of the QuickBooks Online (QBO) mobile app. Try to check if you can now create an invoice. If the error persists or you already have the latest app, clear your app cache. 

The piled-up cache in your application caused this unusual behaviour. Clear your data or cache for this app in the Storage section of your mobile phone to reset the app to its default state.

Here's how to clear app cache or data storage if you're using an android:

1. Open your phone's settings app.
2. Look for the QBO app.
3. Tap the clear data or the clear cache option

Once done, log back into the account and then create and send the invoice. To check the status of your invoices in the QuickBooks Online mobile app, refer to this article: Track the status of invoices in the QuickBooks Online mobile app. It'll show you if you sent the invoice to your customer and if they’ve viewed it. 

After receiving their payment, here's how to receive an invoice payment using the QuickBooks Online mobile app.
