I just did the update and accidentally agreed to importing and/or keeping the fb contacts. How does one remove the facebook messenger contacts from iOS 11.0.3 in contacts? I sure hope there's a way to do it in bulk because it imported thousands of contacts and the former option under settings is no longer there. Any help is greatly appreciated!

contact facebook or look at their support site.
