Q: Explorer tab in AppStore is blank in my new iPad air2

Hello, YourJP.  

Thank you for visiting Apple Support Communities.  

I see that the Explore tab is blank when accessing the App Store.  Let's start with forcing the App Store application to close and restart your iPad.  Once this is done, test accessing this tab. 

Force an app to close in iOS

Restart your iPhone, iPad, or iPod touch

If you are still unable to access this tab, further troubleshooting is needed.  Here are the steps that I want you to try next.  Be sure to test after going through each step.  

On your iPhone, iPad, or iPod touch

If you can't connect to the iTunes Store on your iPhone, iPad, or iPod touch:

1. Make sure that your date, time, and time zone are correct. Tap Settings > General > Date & Time. Time Zone might list another city in your time zone.
2. Make sure that your iOS software is up to date. Tap Settings > General > Software Update to check for updates. You can also connect your iOS device to iTunes and click Check for Update on your device's Summary page.
3. Check and verify that you're in range of a Wi-Fi router or base station. If you're using cellular service, make sure that cellular data is turned on from Settings > Cellular. If you're connected to cellular data, larger items might not download. You might need to connect to Wi-Fi to download apps, videos, and podcasts.
4. Make sure that you have an active Internet connection. Check your device's user guide for help with Internet connection.
5. Check to see if other devices, such as portable computers, are able to connect to the Wi-Fi network and access the Internet.
6. Reset your Wi-Fi router by turning it off and then on again.

If there's still an issue, learn what to do if your device won't connect to a Wi-Fi network.
