I have a chatter in my site record page in my customer portal. When I tagged any user and messaged that user in Chatter, the user is getting a notification. But on clicking on the notification, the user is not redirected to the post. It stays on the same page where the user is is already in. In the dev environment, it is working fine. But in the case of the customer portal, the redirection fails. Please help me with this. It is not a permissions issue, as it is not working for the system admin as well as the customer community plus users.
In my case, I didn't have a detail page created in the portal for the feed item.
In the Customer Portal, we need to create a Feed Item Detail page. Then with the necessary permissions, it will work fine.
