Does not work

I really wish I had read the reviews before upgrading from the free version that cant access dropbox. Complete waste of 2.99. Im trying to open a zip file in Dropbox but when I click on it I get a message that it cannot unarchive the file, which is ironic given the name of the app...it seems like its had issues from the beginning with no support. Avoid this app. Ill be asking for a refund.
