Transactions come up with ‘looks like some have been duplicated’ so when I click on ‘view’ it says ‘oops looks like it’s our fault please try later’… anyone know how to fix this ?

Thank you for posting here in the QuickBooks Community, @lpreacher-icloud. 

It isn't the kind of experience that we want you to come across. I got the steps you need to fix this unusual behavior in your QuickBooks app. 

When the application is not fully functional, performing the recommended basic troubleshooting steps will resolve the issue. 

First, clear the app's cache files. Doing so helps in fixing any sorts of errors in the system. You can follow these steps:

1. Click the Help menu at the top of the screen. 
2. Select the Rest App Data option on the drop-down selection. 

If you get the same result, uninstall and reinstall the QuickBooks app. This way, you can ensure you get the most recent version of the application. 

If you need more insights, I recommend visiting the How to download the QuickBooks Online mobile app article. You can bookmark the website for future reference about the download and installation process.
