I managed to find the issue. We are using another Woocommerse plugin Direct Free Download to allow people to download free products, https://codecanyon.net/item/direct-download-for-woocommerce/6320429. The problem seems to be with using this and yours. Would be great to be able to resolve this as we want to offer this but store everything on Dropbox.
Woocommerse-Dropbox works great when you go through the checkout process!
I’ve copied the link generated by the plugin and pasted it into a browser.
It opens fine this way but when I try clicking in the link on the webpage it still doesn’t work.
