Review of apps don't show up! I wrote 3 reviews for an app, one of them showe up once and the others never did.  This app is almost useless and I feel that others should know that.  So why isn't my review appearing?  It's negative, but professional.
In my knowledge, you can't make more than one review for one version of an app.
So if you tap the review button and you have already made a review, it will show the old review again and you can edit it.
