For the past 2+ years I have been using the same process/code to disabling/clearing activation lock from a device and since December 2 trying to clear the code is returning a 404 error response:

we could not close the activation lock on the iPhone under supervision from our platform. We follow Apple's specifications https://developer.apple.com/documentation/devicemanagement/device_assignment/activation_lock_a_device/creating_and_using_bypass_codes
The request link for closing the activation lock is

The iphone info:
OsVersion: iOS 15
Device model: iphone 12
Steps:
Install the MDM profile on the iphone.
The server pushes the command to install the webclip profile through MDM (the profile is set to not be manually removable).
After installing the webclip profile, the webclip icon will appear on the Home Screen of the phone screen.
When the webclip is no longer used, remove the webclip profile through MDM.
The problem occurs in step 4, the webclip profile is deleted, but the webclip icon still exists on the home screen of the mobile phone, and cannot be removed by tools such as Apple Configurator2.
So what causes this phenomenon and how to fix?
The iphone info:

Steps
Install the MDM profile on the iphone.
The server installs the profile of the disabled camera through the MDM command (access restriction profile).
The server removes the disabled camera profile through the MDM command.
The problem occurs in step 3, the camera icon does not appear on the home screen of the mobile phone but in the App Library.
Is this normal?
