@peter scherrer: The App currently caches collections every 5 minutes to increase the Apps speed. Try waiting a bit and let me know if your collection appears. If that doesn't work, simply uninstall and reinstall the app. We're currently trying to make this faster, or allow merchants to manually update their collections. I'll make sure to respond once we've figured out a better solution.
@Expiry: We'll look into the IE authentication bug, but in the meantime we'd suggest using Chrome. Thanks for updating with more information!
