Facing the same issue, the app still shows "Missing Compliance" and won't let me update the value.
{
"errors" : [ {
"id" : "be7fc499-........",
"status" : "409",
"code" : "ENTITY_ERROR.ATTRIBUTE.INVALID",
"title" : "The provided entity includes an attribute with an invalid value",
"detail" : "You cannot update when the value is already set.",
"source" : {
"pointer" : "/data/attributes/usesNonExemptEncryption"
}
} ]
}
