The license activation works on one device but doesn't work on toher
I have purchased a commercial license for my app. I have already associated my App's package name and yet when I try to activate the license. I keep seeing "Failed to validate product key".
I also had developer license and when I used that, the License Activation works. Why would that be the case?
A colelague of mine, using the same app and same license key is able to validate the license. This seems really strange
