Apparently Microsoft Defender SmartScreen considers the default navigation page set up for Microsoft Edge to be unsafe. Can someone tell me why is it doing this?

Hello!
My Secure Score recommendations have been advising me to set PUA Protection to block mode. Seems easy enough.
This applies to all 9 enrolled machines (9/9 exposed).

However, upon checking I've had a policy setup to enable it in Endpoint Protection > Antivirus for several months.

If I ask Powershell (Get-MpPreference | Select PUAProtection) I am told '2' (audit mode)

If I check the registry I was getting PUAProtection=0, then I ran a PlatformUpdate and got PUAProtection=1

I've checked all the 5007 events and there has been nothing related to PUA for at least the last 2 months.

I guess my issues are twofold:
1. What's the correct way to get this enabled?
2. Is there something obvious I should be doing to make sure the rest of the policy is actually being applied?

I appreciate the effort, but have you tried to listen to the videos? What is your opinion regarding the sound quality?

There is new Secure Now initiative page in Defender XDR portal, but have you tried to watch the dideos? There is a new Secure Now initiative page in the Defender XDR portal, but have you tried to watch the videos? https://security.microsoft.com/securenow

The first 10-min video has two presenters talking about patching; the first is very faint, and the second starts around minute 8 with some scratching and crackling, like he is just fall off the chair... and getting from under the table... While the first presenter is fairly upbeat, the second guy feels really sad. There are persistent background noises, scratching, etc.

Besides, the embedded video player does not allow speed control (which is standard in modern days)

Come on, Microsoft, do you have quality control? Those videos are embedded one step away from the main landing page.
