Workflow Action Buttons Missing in Emails After Upgrading to ERPNext Version 15

I have designed a workflow for the Leave Application in Frappe/ERPNext. Emails are sent to the leave approver and HR when the application is accepted or rejected. After approval or rejection by the leave approver or HR, the employee receives a confirmation email.

Previously, we used to get workflow action buttons in the email. Based on the approval or rejection, the status of the Leave Application would change. This feature was working fine in version 14. However, after upgrading to version 15, the buttons are no longer appearing in the email.

Could anyone suggest a solution to resolve this issue?

Thank you in advance!


thanks! :grinning:
