I'm doing a pilot test of Application Guard with the Edge browser. I have GPOs configured to set my device up in Enterprise-managed mode. The first untrusted site I browse to regardless of the site always ends up timing out. But, then eventually loads after a few seconds. Any subsequent browsing to any untrusted sites will open without issue. Then, if I do a wdagtool.exe cleanup RESET_PERSISTENCE_LAYER to reset the container, I'll get the same problem again. The first untrusted site I browse to will timeout, then eventually load, and any subsequent untrusted sites I browse to will load without any issues again.
