Which is more reliable for Nike sales: app notifications or site emails?

I'm trying to snag some Jordan 4s for my brothers birthday next month and I'm honestly super stressed about missing the drop. I live out in a pretty rural part of Ohio and our internet is so flaky sometimes so every second counts for me. I've been doing some digging and I read on a couple subreddits that the SNKRS app is basically the only way but then I saw a blog post saying the regular Nike app actually sends notifications faster for general restocks. Then some guy on Twitter was swearing that the email links are the only thing that actually works for him.

So I was thinking maybe I should just stick to the app but my logic was that if my service is bad the push notification might just get stuck in limbo. But then if I'm waiting on an email that might take minutes to actually hit my inbox and by then everything is gone. I only have about 220 bucks saved up for this so I really cant afford to miss the retail drop and have to buy from some reseller for double the price. Does the app always beat the email or is it the other way around? I read that some people get early access emails but they never see a notification on their phone at all which makes no sense to me. I'm just sitting here worried I'm gonna be looking at the wrong screen when they go live...
