I uploaded my folder (which contains many files, which is an app) - and shared the link (to myself) for the file that launches the app. When I connect to the link (from my iPad), I get an Error 403. It says I should sign in - which I already am - then it directs me to the help center where I click to submit a request - and get a page, with no form for me to write a request in. I have tested this file - from a different web server - and it does in fact, work. However, I need to use DropBox in order to share these apps with people at work. Thanks for any help!
