In the new Edge 93, when a PDF or other file type is pushed to the browser, there is a flashing down-arrow, and the download indicator now shows up at the top on the right side of the menu bar. While this change of behavior may be acceptable for any standard window that has a menu/location bar, this is an ABSOLUTELY HUGE ISSUE when the user is on a menuless and fullscreen window (launched from window.open). There is no indication of what happened to the download. An average user does not realize that the file has downloaded and they need to somehow open the downloads (such as press CTRL-J, or go to the "opener" window which has a tiny check mark beside the download icon). I've had to field a few tech support calls from confused users as to why the downloads are not working in Edge.
I hope someone from the Edge team can look into this and fix it asap. We have a lot of enterprise apps that are affected by this change in behavior.
