Sizing issues

For the most part, this app is great; but recently, the cover photos I upload dont look sized evenly when viewing FB from my phone. Its fine on a desk/laptop, but...since its a phone app, shouldnt the cover photo look perfect from the phone too, instead of oversized??? Yes. It should.
