I use a separate profile in Chrome for my punting needs, I have just noticed that my default EDGE profile has just nearly autocompleted URLS based on my Chrome punting profile.
I suspect that a recent update to edge has made it look for history, favourites and such from Chrome, but not restricted to the main profile but has started to look in other profiles, or maybe its due to me having a chrome punting session active.
Just thought I would share in-case others do this.
I find a separate profile works better than having to use a private session each time.. well did work well until now
Might be worth just searching your history for this site
