Can anyone give an update on the following ?QB told me that they are aware of the problem of the App Transaction screen not opening, and they are trying to fix it.

We know the importance of your mobile app transaction, Ginger. Let us route you to the support that can guide you further regarding this concern.

As much as I want to assist you here promptly, I'd still recommend reaching our QuickBooks Online (QBO) Mobile App Care Team again as Community is a public forum, and we can't access your account information to update you about the issue.

In the meantime, you can restart your device when you're done trying to uninstall and reinstall the app after updating. This applies to both Android and iOS devices. It will refresh your phone operating system and fix some latency issues.

Moreover, please know that you can also include more details about your issue here as we'll be here to assist you appropriately. You can include some screenshots and the specific app that isn't showing on your screen. Any additional information will be much appreciated.
