We are working with REST APIs of Yammer and sometimes we are getting below exceptions and not able to complete requests.
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.yammer.com/api/v1/users/followed_by/XXX.json?&_=XXX. This can be fixed by moving the resource to the same domain or enabling CORS.
we added web url to javascript origins too. It is observed in IE and Firefox too.
@Yammer team: can you please check. Thanks.
