Why am I unable to enable the pin button from Pinterest button IE11?

Pinterest button IE11

I'm using IE 11 in desktop mode on a Win8.1 tablet and I can't seem to enable the pin button from Pinterest, I download it and it just says not available in the add one
tab. I don't want to have to download Chrome just to o this and I don't want an app.

Re: Pinterest button IE11

It seems to be working now, didn't do anything different.

Gave up on this and had to resort to installing Chrome, where it works well :\
