unable to import portfolio on ipad

[Tx6185]

I just transferred my license to a new ipad, however i'm unable to import my portfolios. when i click the import portfolio button, there is an option to browse, which takes me to a blank screen, and there is a 'get help with cloud services,' which I have read. I do have a cloud service installed (dropbox), but this is not displayed when I click the import portfolio button, nor is there a 'More' option.

Per Dami's suggestion in a different forum I clicked on the Browse button (again), but all I get when I do that is a page saying 'No Recents. Recently opened documents will appear here.' There is no option to add a cloud service.

Please help.
