so this has been sitting like this for several house. Even if I try to cancel it or close iTunes store it still won't change. Anyone else have this issue? It's not just this app it's others as well. I have to reboot my phone for it to go away.
Occasionally this has happened to me on my iPhone 6 ever since I upgraded to iOS 11. It doesn't happen all the time, but every once in awhile they do get "stuck" downloading. I usually just close the App Store and reopen it again and usually that takes care of the problem.
this started around 10.3 for me and is still present on iOS 11. it doesn't get stuck for long but does happen. also doesn't download the update unless i have the app store open. if i close the phone and come back about 5-10mins later - it's still waiting to download and will start up again when i open the app store. annoying.
