Why?

I'm able to begin an upload - but, then nothing at all happens after selecting a file and pressing "upload." I've been struggling with this for about an hour. I gave up and just provided a link to my google drive.

It shouldn't have to be this difficult to pass a teeny-tiny html file.

I was already experiencing a completely different frustrating problem with iReal not functioning as expected - only to be met with, yet more, frustrating problems while seeking help (i.e. posting to this forum).

I'm having a bad day.
