Hello! I see you're having trouble with the payment process at Tropical Smoothie Cafe, receiving a "contact authorization center" message. Let’s work together to resolve this.

You've already tried a few steps like using a new card and reinstalling the app. That's a great start! To help pinpoint the issue, could you please let me know if you're receiving this message only when using the app, or does it happen on the website too?

In the meantime, here are a few more steps we can try:

1. Check Your Internet Connection: Make sure your device is connected to a stable Wi-Fi or cellular data network.

2. Clear App Cache: If you’re using the app, clearing the cache may help. Go to your settings, find the app in your list, and select 'Clear Cache'.

3. Update App: Ensure that you have the latest version of the Tropical Smoothie Cafe app. Sometimes, outdated versions can cause issues.

4. Payment Method: Double-check the payment method details. Make sure the card is activated and has sufficient funds.

5. Try a Different Payment Method: If Google Pay isn't working, try any other payment option available in the app.

6. Contact Support: If the issue persists, please consider reaching out to the Tropical Smoothie Cafe's guest contact center by visiting their Contact Us page for assistance.

Let me know the answers to my questions and how these steps go! Are you satisfied with the suggestions I’ve provided so far?
