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.
