I have a new BRAVIA 5. I tried to sign in to the Sony Pictures Core program using the email address associated with my Sony account.
I keep getting the following message:
Sign-in error.
An error occurred while signing in. Please make sure your email and password are correct.

The login credentials are correct; I've used them to log in to my account here as well. The device is registered (via the TV).
What's going wrong here? The TV is connected via LAN, so it's not a bad Wi-Fi connection. I was able to activate other apps without any problems.
