Leaving a comment on iWork.com using an iPad

Hello all,

I created both a Pages and Numbers documents and then shared them on iWork.com.

When I access the iWork.com platform from my PC using IE or Firefox, I can leave comments on both documents.

When I access the same from my iPad or iPhone using Safari, I can only read them, there is no possibility to leave a comment.

Is there any way to do this?

Thanks,
