Edge Beta intermittently ignoring IE Mode

Hi all, sorry if this is a duplicate question.  We are seeing multiple users with Edge Beta where a site in the IE Mode site list XML will sometimes load in IE mode, and sometimes it won't.  It seems completely random.  Open a new tab or refresh the same tab, 50/50 on if it will load the site in IE Mode.  Edge Stable doesn't have this issue.  We do have our Edge Beta and Edge Stable using the same GPOs and same XML file for IE Mode.

 

Not exactly sure when this started, but its been pretty recent, maybe within the last week that we have heard of.  I can reproduce it on 2 of my PCs with Edge Beta Version 87.0.664.12 (Official build) beta (64-bit) on Win10 1903 and Win10 2004

 

Anyone else seeing this, or have any thoughts?  We have all of our "Test" users using Edge Beta as part of our update ring, so hoping to ease their pain soon.  Thanks!

    We are also now getting reports of this intermittently not working in Edge Stable as well, just not as many.  Version 86.0.622.51 (Official build) (64-bit)

      SteveSta Hi Steve - Thanks for reaching out!  Yes, there was a recent post on the Forum from someone reporting the same issue (Problems with Enterprise Mode (IE Mode) in recent builds ? - Microsoft Tech Community)

       

      We've also been getting reports of this issue from a few other sources but we still haven't been able to get a consistent repro.  

       

      Like I mentioned in the other post, it would be very helpful to get your logs, repro steps, traces and other information we can use to troubleshoot.  Would you be able to file a customer support request?  Because of the sensitive information/PII that can be in the data we ask that you work with Support Team.  They should be able to gather the necessary information for our team.  Thanks for your help!

        This is happening to us currently (it wasn't happening as of 2 weeks ago) and I can recreate it at will. chrome_debug.log pasted into Word doc below. I can't find any smoking gun causing it but I can cause it easily. On the log below you can see it loads one of my IE mode sites on line 1558, but when I try the exact same site 3 minutes later on line 1781 it loads it in Edge mode. I tested on the current Beta edge (87.0.664.18) and it is still occurring on it.
