Was just wondering what the difference was between modern and desktop IE 11.
I seem to run into problems when using the desktop version, and the problems can be fixed by using modern.

For example when creating a document in icloud.com, it will not let me create a new one in desktop IE but in modern it will.

When watching youtube videos some videos will not play in IE desktop without compatibly mode and when in modern they will play either way.

There are some other types of problems that are fixed as well.

So what is the real difference between the desktop and modern IE
