Unable to reach IDP Initiated page of ADFS in Server 2016

Noticed IDPInitiated signon page is not loading by default in Adfs 2016 as it is loading in pervious versions.

Default IDP URL : https://adfsname.domainname.com/adfs/ls/idpinitiatedsignon.aspx
In my case, https://sts.windowstechpro.com/adfs/ls/idpinitiatedsignon.aspx

Ideally, in ADFS 2016 it is disabled by default.

Run the below command to see status of the IDP Initiatedsignon page.

Get-AdfsProperties | Select-Object EnableIdpInitiatedSignonpage

Now, To enable the IDP Initiatedsignon page run the below command,
Set-AdfsProperties –EnableIdpInitiatedSignonPage $True

restart the adfe service in all the adfs 2016 servers using the command

Restart-Service adfssrv
it can be done using services.msc as well.

It is all done, try to load the Idpinitiated signon page
