Hi there! I understand your "My Inter Card" isn't working with your Earnify app, and I'd love to help you get that sorted out. To get started, could you share a bit more about what's happening? For example, are you unable to add the card to the app, does payment get declined at checkout, or is there an error message you see?

Meanwhile, here’s a general step-by-step you can try to troubleshoot this issue on your Android 10 device:

1. Check Card Compatibility and Balance
Ensure that your Inter Card is supported by Earnify and that it has sufficient funds or credit limit to cover purchases.

2. Update and Restart the App
- Open the Google Play Store.
- Check if there’s an update available for the Earnify app and install it.
- Once updated, close the app completely and restart your phone.

3. Remove and Re-add the Card
- Open the Earnify app, go to your payment methods.
- Remove the Inter Card if it’s already added.
- Add the card again carefully by entering all required details.
Sometimes re-adding can refresh connectivity.

4. Clear App Cache and Data
- Go to your Android Settings > Apps > Earnify.
- Tap on Storage, then Clear Cache and Clear Data (Note: this may log you out; have your login info ready).

5. Check Network Connection
Ensure you have a stable internet connection, as intermittent network issues can cause payment failures.

6. Try Payment at Pump or Store
If you’re trying to use the Inter Card directly at a pump via the app, try using the Earnify app with your phone number or linked card at the register instead to see if it accepts the payment.

If you’ve already tried some of these steps or if you’re seeing a specific error code or message, please let me know. That way, I can dive deeper or suggest next moves, like contacting support for your card provider or checking for known app outages.

Are you able to tell me more about your experience so far?
