Markdown Import

Hello, when I go to import some Markdown documents, I will choose a few Markdown documents to import. The import button will light up, I will click "Import", and then I get an error that just says "Failed to download". I've tried importing many different Markdown documents, I've tried to import them from both my local and from my iCloud, and still getting this error.

Can you please help? I really am liking Meebot, and if I can see how things import and it meets my liking, I will go ahead and sign up for the service.
