I'm having a small problem with the windows store. I have uploaded all the required graphics in the submission, and the app has all of the required graphics (including box and wide tile images).
In the store however, the app entry is using a wide image. The problem is that the wide image it's using is actually a box image , that's stretched.
Any ideas what's going wrong?
I've been in touch with Microsoft support regarding this bug. It was fixed just two days ago.
You just need to upload new package/version of your Windows 8.1 app now and the proper icons will be used for Windows 8.1 Store!
