Edge forcing switch profiles when using any .local domain or IP address

AlexB This got me as well.  The change is actually mentioned in the Edge 119 release notes:
https://learn.microsoft.com/en-us/deployedge/microsoft-edge-relnote-stable-channel#version-1190215144-november-2-2023

As it says in the details of the new SwitchIntranetSitesToWorkProfile policy, the default, if not configured, is to enable the behavior:

https://learn.microsoft.com/en-us/deployedge/microsoft-edge-policies#switchintranetsitestoworkprofile

I would assume that the majority of users that have a work profile are internal/corporate.  I think, in such context, this seems to be a sensible default.

Hope this helps,

Daniel
