I renewed my subscription but can’t customize in the app keep saying subscription problem.

I can see the urgency of getting your QuickBooks Online (QBO) app and subscription issue fixed, spicesfoodcateri. Let's perform some troubleshooting steps so you can use the system accordingly. 

Before we begin, can you share with us the exact error message you receive when doing customization and creating invoices? This can help us identify the problem and give you the right solution.

The QBO mobile app uses a cache to speed up your experience in performing your tasks. When the cache is full, you may encounter unusual system responses. Clearing your app data can refresh the system and remove older files causing these issues.

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

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 persists, I'd recommend uninstalling (tap and hold the app icon) and reinstalling the app. This is to ensure the version you'll be using is updated. 

I'm also adding this 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 for the international version of QBO). It contains a comparison chart between Android and iOS devices.
