Hello there, Glenn.

I understand how significant utilizing your scanner without encountering some changes or issues. I'll explain how you can fix this to help you perform your tasks smoothly. 

Before I start, may I ask what specific apps are involved when you connect the scanner to QuickBooks? You could also share more details about this so I can guide you on the proper and accurate steps to resolve it.

Since you're routed to the Google Play App Store while using your scanner, this could be due to account or internet connectivity. Thus, let's make sure you open and log in to your QuickBooks account and ensure your internet connection is stable before using the device, so you won't revert to the app store again. 

Moreover, here are the outlined steps to pair your device to your QuickBooks company file:

1. In the QuickBooks Edit menu, select Preferences.
2. Choose Items & Inventory, then go to the Company Preferences tab.
3. Click the Advanced Inventory Settings option.
4. On the Site Operations tab, hit the Add button. 
   
   
    
5. Open the scanner on your mobile device, then enter the passcode you received from the program.
6. Select Link, then Yes.
7. Once a success message indicates that the scanner is linked successfully to your QuickBooks company file, tap Next.

For a more detailed procedure for setting this up to QuickBooks, I'll attach this article as your guide: Setup and use the Warehouse Manager in QuickBooks Desktop mobile.

In case you're experiencing errors in setting up or linking your devices, here's a reference to help you address and resolve them: Troubleshoot QuickBooks Desktop mobile app.

If you already have a list of barcodes, you can import them into the system. 

With all this information, you should be on track to finish setting up your scanner with ease. However, if you have any questions about this, or issues while navigating QuickBooks, I'm always here to assist in whatever way I can. I hope you have a great day!
