If you're unable to use the 2ndLine app even after subscribing, here's how to troubleshoot the issue:

1. Verify Subscription Status:

Open the "Settings" app on your device.

Tap your "Name", then "Media & Purchases" (you might be asked to sign in).

Select "Purchase History".

Look for the "2ndLine subscription" entry.

2. Identify the Problem:

  • If the subscription is listed under "Pending", it means the payment is not yet settled with Apple. 
    • In this case, you may need to wait for "Apple's confirmation", which can take some time. 
    • You can read more about this process on Apple's website.
  • If the subscription is listed as "Active" under a recent date but the app still doesn't work:
  • If the subscription is in a grace period: Ensure that your credit card has sufficient balance. If App Store is unable to charge your credit card, it will attempt to do so for the next 7 days. If payment is not successful after this period, your 2ndLine subscription will be canceled.

Additional Tips:

  1. Restart your device: This can sometimes resolve minor app glitches.
  2. Check for app updates: Ensure you have the latest version of the 2ndLine app installed.
  3. Check your internet connection: A stable internet connection is crucial for app functionality.
