We are aware of an issue that is preventing users from creating Templates. Our engineering team is currently investigating it. Please wait for new updates, which will be shared here as soon as they are available.

Details: When creating a Template message, you might get the error: `Invalid payload ({"error":{"message":"Error validating access token: The user has not authorized application x.","type":"OAuthException","code":190,"errorsubcode":458,"fbtraceid":"y"}}) `
