Need to modify Application Page Link for emails being sent out.
The link provided in the email notifications should point to the appliance from which it was sent, whether it was the Primary or the Replica.
This feature has been added in the 2.5.919 release. Please upgrade to the 2.5.919 version or higher.
In email notification configuration added a new setting: If email is generated from a failed over replica, send additional link to the replica network address. If selected, the email will include a link from the failed over replica as well as the link from the original primary.
