I click on “Download”, a box appears saying that my download has started, but actually nothing happens.
Step 1: Open “New Private Window” (Firefox) or “Go incognito” (Chrome).
Step 2: Add “m.” before your box.com link. It will be come “https://m.app.box.com/s/%5Bletters%5D”
Fox example: your old link is https://app.box.com/s/…, your new link will become https://m.app.box.com/s/…
Or you can do the other way around (step 2 then step 1).
Step 3: Click on Download and enjoy!
