We renewed our subscription and we still cannot use the app . Kindly do the needful .

I'm here to ensure you'll be able to use the QuickBooks Online (QBO) mobile app accordingly.

First, let's access your QuickBooks account through the web interface. This is to check if you're subscription has been fully renewed. If you can log into your account without issues, let's perform some troubleshooting steps to rectify the mobile app issue. 

You may have an out-of-date version of QBO and your device, preventing you from opening and using the QuickBooks app. It is necessary to update them to have access to new features and fixes. Here's how:
 

1. Open the App Store/Google Play Store on your device, then tap your profile icon at the top of the screen.
2. Find the QuickBooks mobile app in the Available updates section.
3. Select Update.
    

If you're still unable to use the app, let's refresh your app data. Here's how to :

1. Go to the More icon at the top right corner of the screen.
2. Choose Settings.
3. Select Refresh Data and choose Yes.

If you're using an iOS device, here's how:

1. Go to the Menu icon at the top left corner of the screen.
2. Choose Help & Feedback.
3. Select Refresh Data and Refresh.

In case the issue remains, I'd recommend uninstalling and reinstalling the app. 

Additionally, here's an article to learn more about the QBO app features available on supported mobile devices: Compare mobile app features (the article is for the US region but also applicable to the international version of QBO). It contains a comparison chart between Android and iOS devices.

Keep in touch if you need any more assistance with using your QBO mobile app, or if there's something else I can do for you. I've got your back. Have a good day!
