Internet Explorer Mode Flip-Flops Between On and Off
Not sure if this will help anyone, but one of the other things I discovered after much frustration was that if you add an enterprise site list or make any changes to it, Edge will take approximately 1-1.5 minutes to load the new list the next time it starts up.
You'll see an EmieSitelist.xml file pop into %localappdata%\Microsoft\Edge[version]\User Data when it's loaded. Prepopulating this file unfortunately does not change this behavior.
To clarify as well, I noticed that even if I specify a sites list in Edge at HKLM\SOFTWARE\Policies\Microsoft\Edge, IE mode will not work properly unless the Enterprise Mode Sites List is configured for Internet Explorer at HKLM\SOFTWARE\Policies\Microsoft\Internet Explorer\Main\EnterpriseMode).
Interestingly, if you configure the sites list in Edge and then remove the list from your IE Enterprise Mode key or delete the key entirely, it will continue to work on that machine. It just won't work if you start with just the Edge key on a new machine.
Haven't tried this in group policy yet but I expect it would work the same.

Unfortunately using the Enterprise Mode List did not make a difference, it's still flipping back and forth between IE and Edge with every click. Strangely enough that I had to force update the list in edge://compat/enterprise in order for it to accept, it didn't import automatically. Attached I have the Internet Explorer mode diagnostics information found in edge://compat/iediagnostic, just in case it contains crucial information.

We configured the enterprise mode site list and it fixes this issue only on my machine (developer machine but treated as normal user machine). Whereas, it doesn't work on system admin's machine. The different between my account and system admin account is that, I have list of trusted sites in Internet Explorer that is managed by IT team. For my system admin, he has to manage his own trusted sites locally in Internet explorer. Still not sure what's causing the issue.
This diagnostic information is of my machine (account).
