I'm starting to question the validity of some of the notifications. The Coquitlam store is responsible for 9/10 notifications I get, all for a SG (despite my looking for both colours), and I've never, ever seen it available in the app. Usually I'm staring at my phone when the notification happens, with an order queued up in the background. It takes me 2-3s to get to the "pick your store" page. Nothing, ever.
When the notification is for other stores, I frequently can pick them as a pick-up option, but the stock is gone by the time I complete (another 9-10s).
Looks like I'm waiting for my ordered phone to finish it's Incheon vacation (there since 8th), and be delivered into my hands on Nov 14th Nov 15th "Scheduled delivery information is not available at this time. Please check back later."
