Form Attachments upload

Form Attachments upload

I have been using Zoho Form and have been uploading photo data to Dropbox, but Dropbox has recently been updated and I can no longer open photo data from the form.
I am trying to change the location of attachments in Zoho Form again, but I can't get it to work.

I would like to be able to access the existing data, so I would like your advice on how to deal with this problem.
