Iphone 8 App Store Not Working No Fixes Have Helped So I recently got off android and bought the Iphone 8 with IOS 11.0.2 running. Everything was good until about a day after I bought it. I noticed I couldn't download apps anymore. I would sign into my apple id then the app store would tell me its all good then it just gave me the spinning circle and never downloads. I have tried restoring twice and once with a new apple id and still same problem. I have tried going to the At&amp;t store to get it fixed yet still nothing they even gave me a replacement phone. Even with that phone its the same issues. I can download apps for about a day then it just shuts off again. Anyone know anything that could fix this? Or am I just going to have to wait until IOS 11.0.4 comes out. FYI this issues is on both 11.0.2 and 11.0.3 I did try updating it. Any help at all would be very appreciated. Thanks
I had the same issue with my new iPhone 8 Plus. I came from an iPhone 7 and never had that issue, although it seems relates to the Apple ID.

What i did to temporaly work around it was to shut down the phone and turn it on again. Now i was able to download and update apps again.

Also you can try to reset your keychain.

Settings > [Your name]  > iCloud > Keychain

Also, try updating to iOS 11.0.3 
At the time i had the issue i was with iOS 11.0.1
