Original Post:
Currently when using the Turnitin App on an Apple device, users might have difficulty accessing a paper’s information using the information button. 
It appears that there is no information loading in the window, but this is a rendering issue not an app issue.
If you scroll up and down on the information box which opens, the information gradually appears.
