Hi there! I’d be happy to help get your cameras working properly after your subscription purchase. To make sure I fully understand, can you tell me if the app is repeatedly asking you to renew or purchase the subscription even though you already paid? Also, have you tried any troubleshooting steps already, like restarting the cameras or the app?

Meanwhile, here's a common and straightforward set of steps to try that usually clears this type of subscription recognition issue:

1. Log Out and Log Back In: Sometimes the subscription status doesn’t sync correctly. So, sign out of the camera app, then sign back in with the account that purchased the subscription. This can refresh your subscription status.

2. Update the App: Ensure your camera app is updated to the latest version available in your app store. An outdated app may not recognize your subscription properly.

3. Restart Cameras and Router: Power cycle your cameras and your Wi-Fi router/modem. Sometimes network glitches can affect subscription validation.

4. Reinstall the App: Uninstall the camera app completely from your Windows device, then reinstall it. This can clear up corrupted cache or settings related to your subscription.

If you’ve already done these or still face the issue, another thing to check is whether your subscription is correctly linked to your account in the app or the service provider’s portal. Sometimes a missing purchase preference or default address on the account may cause this problem.

Please try these and let me know where you get stuck or if the problem persists. I’ll guide you further from there.

Are you satisfied with this initial solution, or would you like me to assist you step-by-step through these actions?
