I've submitted a game to the win store, which has been rejected twice because the testers were dissatisfied about the snapped view. Bizarrely, I used the same default snapped view that I used for my previous game.
I also noticed they picked up on a few other things that they completely ignored for my last game.
Anyone else getting these annoying issues with MS now? I guess it's possible I've had the misfortune of getting a particularly retentive tester :/
Sadly, this means I miss out for the Win8 compo, but ah well them's the breaks.
p.s. Here's the most recent suitably vague report - no definition of "instability"
Notes from Testers:
A:: When reviewing the app, our reviewers observed instability issues when using snapped views with this app. More information on snapped views can be found here: http://msdn.microsoft.com/en-us/library/windows/apps/hh465371.aspx
