KPE: Invalid license on KnoxSDKSample

I'm new here. I downloaded KnoxSDKSample and import to Android Studio 3.5.
I changed String KPE_LICENSE_KEY in Constants.java with KPE Development Limited LICENSE NUMBER.

When I try to activate license, it show Toast "Failed to validate product key" and "KPE: Invalid license".

How to resolve it?

Can you please check to make sure the license that you have is valid?

I will include a link which will allow you to copy-paste your license and check its validity.


(You will need to be signed into your Samsung Account first).

At the bottom of the dashboard page, in the section labelled "Tools", there will be a text-box allowing you to copy-paste your key to see if it's valid.
