I am following a number of posts and examples in the PlayFab community and the API Policy Guide, but I keep getting the following error: "Failed to save new global policy: Invalid action * in statement". The rest of my policy is the default policy.
Adding:
{
"Resource": "pfrn:api--/Client/UpdateUserTitleDisplayName",
"Action": "*",
"Effect": "Deny",
"Principal": "*",
"Comment": "This statement denies request to UpdateUserTitleDisplayName"
}
