I have to laugh at this: "Edge is lightly managed, with users able to access all features, while in Edge for Business, IT can control which features are available to users"
They're on the same device. What is the point in us having policies on corporate devices if you can then just decide to have another uncontrolled sorry "lightly managed" browser on that same device.
This is beyond belief.
Corporate devices, need to be controlled by corporate. Stop making changes with no notice, stop releasing features without controls, stop telling people who are p'd off by your mistakes, that they should contact support for assistance with "their unique issues", stop creating more work for those people you expect to log these tickets who you've already created more work for by messing this up in the first place
