Delete and reinstall again
When it gets stuck on "downloading updates," quit the app, then find the app on the homescreen and delete it with a long press and then select "delete." Then come back to App Store, and download it again to give it another try. Worked for me.
Best mobile futures platform
Quick and very customizable for a mobile trading app.
Frozen from the start
Downloaded the app. When it opened, the entire screen was ghosted with a note ‘checking for updates’ and was completely dead.
