Add Images and Designs not working on touchscreen iOS

 While attempting to implement Fancy Product Designer on my WooCommerce/Wordpress site everything seems OK, however when I try and use FPD on an iOS device (iPad) I am unable to actually add an image to the design as I could on the desktop.

For example:

• I can select 'Add Image'
• I CANNOT select 'Click or Drop Images Here' to upload an image,
• If I select to use a Facebook image, I can select an album, and review the photos from my facebook account.
  
• I CANNOT select to insert it into the design.
  

Any ideas on where I need to look to resolve this issue.
