Hi there! I'm really sorry to hear that your DualChat subscription isn't working despite being paid for a year. That can be quite frustrating. Let’s figure this out together.

First, could you confirm if you received a confirmation email after your payment? Sometimes if there was an issue during the payment process, the subscription might not activate correctly.

Next, please check if you are logged into the correct account that the subscription is tied to. Sometimes people have multiple accounts and might log into the wrong one.

Here are some initial troubleshooting steps I recommend:

1. Log Out and Log Back In: Sometimes, just refreshing your session can help.

2. Check Your Subscription Status:
- Go to the settings or profile section of your DualChat account.
- Look for a subscription or billing section to see if your subscription is active.

3. Restore Purchases: If you have this option in the settings, it might help in case the app is not recognizing your subscription.

If you've tried these steps and the issue persists, I can check further details for you. It might also be worthwhile to ensure your payment method is still valid, as expired cards can lead to subscription issues.

Let me know what you find!
