Hi everyone,

We are trying to configure Workflow Notification with Approve/Reject action for processes (Promotion, etc..) according to: https://docs.oracle.com/en/cloud/saas/procurement/18b/fapaa/analytics-modification.html#FAPAA2953801

Currently the email notification is being sent with broken links for action buttons, such as: "http://biptokenapprovebiptoken/ " while we are expecting it to be a "mailto:" link that creates a mail with To, Subject and body ready to be sent. 

About a month ago we didn't have this problem, and the action buttons were working as expected. I've added a screenshot of an old mail with working action buttons links.
