If you're experiencing an error where the synchronize groups button on SharePoint has been disabled, this is expected behavior following Update 4. This occurs because we have now enabled the identity microservice for Cloud/Appit customers. The identity microservice automatically synchronizes identities and updates from AAD and SharePoint to K2. For more information on the identity microservice, please refer to the following KB article: http://help.k2.com/kb001958
Hope this clears up some confusion!
