Swift playgrounds installations problems

If anyone having trouble installing the Swift Playgrounds App ? For some unknown reason once the App is installed, then when is time to open the first lesson the downloading process get in a paused state when almost the downloading circle is about to complete rendering the App unusable. I used to run this App without any problems when my iPad was iOS 10 but since last year when iOS 11 came this App does not work properly anymore. I even reset my iPad to the factory settings but still it doesn’t respond. I have an iPad Pro 9.7 WiFi plus cellular. I have only used 43.4 GB of 128 GB of total capacity. Does anyone can help me?
