Dropbox Integration Error

For some reason, our integrations with Dropbox on various forms seem to have broken today. Can you please fix or instruct ASAP? 

I have tried to integrate a test form to my Dropbox account and it seems to be working fine. Are there any particular issue(s) that you are experiencing on your end? Can you help us identify the issue by providing us more details and a clearer description, please?

We will wait for your response.

Thank you.
