Windows 11 Pro and WSA not always recognised as Default Security App ?

Hi Webroot Community
I was wondering if anyone else has noticed WSA not always being recognised as the Default Virus and Threat Protection App in Windows 11.
I was looking at the Windows 11 Security Centre and noticed the PC had reverted to Windows Defender as the Default Default Virus and Threat Protection App.
The other thing I have noticed is on Bootup the Security Centre takes a couple of Minutes to Decide the Default Virus and Threat Protection App.
I did a fresh install of Windows 11, and  WSA was the first app I installed and Windows Security took a couple of minutes to acknowledge WSA.
Kind regards
