FAQ Q: Why does the discount in the app not match the discount at the store? A: It probably means that the data about prices is not updated on IsThereAnyDeal.com yet. The data is aggregated in multiple currencies from a lot of stores, so some delays are to be expected. This also applies to coupons, bundles, and review scores. Q: The app is taking a long time to load and/or crashes. Do I have to submit a bug report? A: Sometimes there is a high load on the servers due to some major sales. There also might be maintenance going on. You can always check the current service status on IsThereAnyDeal.com. Q: Will these keys get my Steam account blocked? A: No, all the stores within the app are legitimate key resellers, so there should be no "grey" keys whatsoever. Q: I enabled notifications, but I'm not receiving them. What's wrong? A: Observatory doesn't use push notifications; it utilizes local notifications. For notifications to function, the app needs to be in a suspended state. If it's terminated (removed from your recent app list), background operations cease. If you want to manually check for recently discounted games, select the Discount Date filter on the Waitlist page. DISCLAIMER All the data about prices, stores, coupons, review scores and discounts is provided by IsThereAnyDeal.com. Observatory is not affiliated with IsThereAnyDeal.com in any way.
