Can anyone help. Since the new app update I now can’t edit my transactions eg from deposit to sale receipts, change payee details etc?

Welcome to the Community, @reeds1000.

When QuickBooks has unexpected behavior, let's try resetting the app data to clear the cache and refresh it into its default state. Before doing so, let's ensure that your QuickBooks Online (QBO) mobile app is updated as well as your phone's OS. It helps your application work continuously without interruptions. 

To clear the app's cache files, here's how:

For Android devices:

1. In your QBO mobile app, select the Gear icon. 
2. Choose the Refresh Data menu.
3. Click Yes. 

For iOs devices:

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

Once done, check if you're now able to edit your transactions. If the issue persists, let's try to uninstall and then reinstall the app. You can get more information in this article: How to download the QuickBooks Online mobile app.

Touch base with me after trying these steps. I want to ensure that we get this resolved as soon as possible. Enjoy the rest of your day!
