Units do not download – English Grammar in Use: Sample Review

Downloaded this app and purchased two of the units. It’s been three days and I’m still waiting for it to finish downloading. I’ve restored the purchases, deleted the app and reinstalled it, restored the purchases again. Still says unit is still downloading, try again later. This app has been a complete waste of my time and money.
