Hi there! I understand that you’re experiencing an issue with the CVS Health app not allowing you to add coupons, and it displays an "unexpected error occurred." Let’s work through this together!

First, could you share a bit more about what you’ve tried so far? For example, have you tried restarting the app or your device? Sometimes a simple refresh can resolve minor glitches.

If you haven't done that yet, here are a few steps to try:

1. Restart the App: Close the CVS app completely and then reopen it.
2. Check for Updates: Make sure you have the latest version of the CVS app. You can check for updates in the Google Play Store.
3. Clear Cache: Clearing the app's cache can often resolve unexpected errors:
- Go to Settings on your device.
- Tap on Apps or Application Manager.
- Locate the CVS app and select it.
- Tap on Storage and then select Clear Cache.

If you've already done these and the issue persists, there might be some ongoing issues with the app based on user reports. I found some conversations indicating that others have faced similar problems recently, often related to the app being glitchy at times.

In such cases, I recommend trying again later to see if the issue resolves itself or contacting CVS support directly for guidance. You can reach them at [email protected] for further assistance.

Are you satisfied with the solution I provided, or do you need help with anything else?
