Missing basing functionality

I really wanted to use this app after reading about it on macstories.com, but even though I love triaging with built in actions I cant use the app. I cant attach files form iCloud or Onedrive to me email messages. This is extremely frustrating. I am not going to change where all of my work files are stored. This is disappointing, because I really like many features built in to dispatch. For this reason I am sticking with Spark as my go to iOS mail app. Im very disappointed that I cant use this interesting app
