Known issues

Symptom Workaround
When updating to Windows 10 v1909 or v1903, you might encounter a compatibility report dialog with What needs your attention at the top.  The full error message is – Continuing with the installation of Windows will remove some optional features. You may need to add them back in Settings after the installation completes. This compatibility warning comes to view when LOCAL SYSTEM accounts are blocked in Windows Defender firewall from accessing the internet through HTTP. This is occurred because of Dynamic Update being unable to download the required packages. Enable HTTP access for the Windows 10 Setup Dynamic Update (DU) FROM the LOCAL SYSTEM account. Now start the installation of the update again and you should not encounter the warning. Moreover, you can click the OK button or use the /compat IgnoreWarning command to ignore compatibility warnings. However, this might also ignore additional warnings that might affect your device.

The tech giant is trying to resolve the issue and will provide an update in a further release.
