I paid my subscription days back but the message to subscribe keeps popping so can’t use the app

Hi there, mwyclef.

Have you tried logging in to your QuickBooks Online account using a web browser on a laptop or desktop?

If you had the same problem when signing in through a web browser on a laptop or desktop, I recommend double-checking your billing information and updating it from there.

Like this:

1. Sign in to QuickBooks Online as a primary admin.
2. Go to Settings ⚙, then Account and settings.
3. Click on Billing & subscription.
4. To update your billing info, select Edit ✎next to your payment method.

You can check out this link for more details: Update billing, payment, and subscription info in QuickBooks Online.

Otherwise, if everything looks good after you sign in using a browser on a laptop or desktop, you can uninstall and reinstall the QuickBooks Mobile App. Use this link as a reference: How to download the QuickBooks Online mobile app.

Let me know how it goes or if you need further assistance. I'll be here to lend a helping hand. Have a great day!
