How to add link back to classic PPM from new UI of 15.2. Its only showing Projects, Resources and Timesheet link.
Thi Shiva the last link should be the back to classic UI, I see its missing in your case and it could be because of some incorrect configuration. Did you enable the new UI from classic UI?
Yes, Its enabled in Classic UI.
is there any other place it needs to be changed?
No that is the only place where it needs to be enabled. Are you using the same URL which is updated in the HTTP/HTTPS entry URL followed by /PM
You need to have Classic PPM - Navigate right given to see the link
Thank you Suman
