When I check for updates on an iOS device of mine, the results takes quite a bit of time to get listed. And even sometimes they don't and I've to restart the app by killing it. Although the speed when downloading something from the App Store(whether it be a new app or an update) or any other Apple store is pretty good. It's just the updates trying to get listed that takes quite a bit of time.
This problem isn't just tied to me as well. It happens in other devices that belong to my other family members whom I use the same store account for purchases.
In my opinion, this isn't a network problem as well because everything other than trying to get the updates listed is pretty fast.
I would have said this is because I live in Turkey and I'm in the USA App Store with the help of store credits but then again everything other than trying to get the updates listed is pretty fast!
Also our Mac updates show up pretty quickly.
So what do you think might be the problem?
