I was looking at the change for System.Boolean CMS.Newsletters.SubscriberNewsletterInfo.SubscriptionEnabled in the API Change list for 8.2 to 9.
It recommends Service ISubscriptionService> Entry IsUnsubscribed(subscribedId, newsletterId);
I am replacing subscriber.SubscriptionEnabled = true;. Should this ISubscriptionService be IsSubscribed? Maybe I am reading it wrong.
After looking at the code closer the subscriber.SubscriptionEnabled was not needed.
My question got truncated.
