When i use the menu button top left select customer option, then choose a customer, look at or edit an invoice the return arrow disappears top left and i get stuck

Let's perform some troubleshooting solutions to get this sorted out, @littlehairleft.

I've checked here on our end and there's no reported case where the Customer menu or the return arrow when editing an invoice is unresponsive. There are times when a browser's cache data becomes full of frequent access to web pages or is damaged. This causes odd behavior when using QuickBooks Online (QBO). To better isolate this issue, let's try signing in to QBO using a private or incognito window. This mode doesn't use the existing cache data and helps us confirm browser-related issues. Here's how:

• For Google Chrome browser: Ctrl + Shift + N
• For Mozilla Firefox browser: Ctrl + Shift + P
• For Safari browser: Command + Option + P

Then, try accessing the Customer menu or editing an invoice again. 

1. Go to Sales on the left menu.
2. Choose Customers and choose a customer name.
3. You can also click the Invoices tab. Then, tap the Action drop-down and hit View/Edit.

If it works, go back to your regular browser and clear the cache to delete those temporarily stored files and browsing history. The overtime collection of data can create corruption, however, removing this should fix the issue. You can also use supported, up-to-date browsers to roll out the possibility of a browser-related issue.

I'd like to know how you get on after trying the steps as I want to ensure this is resolved for you. Just reply to this post and I'll get back to you. Take care always.

Hello i am using the app for the ipad from the dashboard when i touch the menu top left and select customer, choose a customer and not open or edit an invoice i can return to the dashboard however when I select a customer invoice to open or edit or create a new invoice the back arrow disappears i can continue to view edit invoices for the same customer but the only way back to the dashboard is to close the app and restart it. I tried deleting the app and reinstalling but the issue is still there

Thanks for getting back to us, @littlehairleft. 

As an additional insight, this is probably caused by a system delay in the QuickBooks Online app.

Let's do a few basic troubleshooting steps to fix this issue by restarting your QuickBooks Online app on your iPad.

Then, clear the application's data by going following the steps below:

1. Click Menu ☰ and select Help & Feedback.
2. Select Refresh Data.
3. Then hit Refresh.

You should be able to see your manage your invoices. However, if the problem persists, I'd suggest contacting our Customer Care team. They can create a case ticket to report the issue to our engineers to investigate this problem.
