For the past 2+ years I have been using the same process/code to enable and disabling/clearing activation lock from a device and since last week trying to clear the code is returning a 404 error response:
<head>
<title>404 Not Found</title>
</head>
<body>
<center>
<h1>404 Not Found</h1>
</center>
<hr>
<center>Apple</center>
</body>
</html>
I can confirm that the request looks ok and all the necessary params are being sent as expected.
