Q: app tiles are blank and will not download

Hello DAVIDFROMHEADLAND, 

Thanks for using Apple Support Communities. 

I see that apps are appearing blank, and this is preventing you from downloading apps on your iPhone 6. I understand how important it is to make sure that you are able to download and use all of your apps. I have several things I'd like you to try. 

First, it appears that the App Store app isn't responding like it should. Please use the resource below to Force close the App Store app and then test again to see if you get the same result:

Force an app to close on your iPhone, iPad, or iPod touch

Second, please go ahead and give your iPhone a fresh restart and then test. The article below will help:

Restart your iPhone, iPad, or iPod touch​

And finally, if you still have an issue, log out of the iTunes and App Store on your iPhone and then log back in. To sign out, go to Settings > iTunes & App Stores > tap on your Apple ID and select Sign Out. Sign back in on that same screen. Then, Open the App Store and test once more to see if you get the same result. 

Cheers!
