When checking our Purchase History at WindowsPhone.com we noticed that we are missing our purchase history for our WP7 phones (even when we choose our WP7 phones from the drop-down). Also, when viewing the WP7 phones it only shows what we purchased with our WP8 devices.
I checked the exact same purchase history a week ago (before I bought the WP8 phones) and it showed all of the app purchases for our WP7 phones. Something seems to have gone wrong with WP8 on WindowsPhone.com. The purchase history is all messed up.
