You’ve been logged out of your Endel account after an update

1. First, try logging in.
2. If that fails, tap "Restore Subscription" on the in-app Settings screen (the user icon in the upper right corner). Your subscription will resume in a few moments.
   
   Don't worry, neither the App Store nor the Google Play Store will let you have two Endel subscriptions on the same device. So, you'll never pay twice — even if logging in with an email and then with Facebook, etc.
