Notifications about comments
At the moment, there are no notifications about comments. It would be great if the writer of a timeline post received a notification when people comment on his post. For now, you have to check all your comments from time to time, e.g. if you are waiting for a partciular answer.
If you don’t receive comments on a post you have written then this is a bug. So could you please double check whether this is the case? If so please report this to our service desk: https://www.service.coyoapp.com/
If you are talking about comments on blog articles or wiki articles – you are right. This is an open issue: http://community.coyoapp.com/forums/306010/suggestions/30997528
