Ionic 4 app not working in IE 11

My Ionic 4 app is not rendering in IE 11. But they say that Ionic is supported in IE 11.

I got errors on the console as well. There is no way to fix?


once you check google chrome, still error repeat ,
could you share your code hereā€¦

there is no issue in chrome , edge, firefox
Only IE causes the issue and ionic app is not rendered.
