Answer 1

Angular 9 out of the box should work absolutely fine in IE11 now.

I tried all of the suggestions listed here and none of them worked. However I did manage to track it down to a specific library I was importing in app.module (ZXingScannerModule to be precise). If your app is failing in IE11 on the first page, try removing libraries one at a time and check in IE11 - it was completely missed in all my build warning errors. If you do find this is the case, then consider compartmentalising the area of your site which uses this library as a lazy loaded module.
