IQANrun App for Apple - Where do you place project files?

I've installed IQANrun ver 5.01.4 on a new IPAD Pro 10.5 with iOS 11.3.1

I am trying to place a .idax project file ver 5.02 onto the tablet so I can load it through the app.

I purchased the PRO capabilities to allow download from the app.

Under "Manage Files" if I select Dropbox, the app pops up "No Dropbox access".  It goes on to say that a web form will display next but none appears.  So I'm unable to use the Dropbox method.

Where can I place a file so the app will find it?  (similar to IQANsync where the app looks in On My Pad/IQANsync)
