Well, Dropbox just closed my request from a few years ago, and there are others that have posted similar. This is not resolved yet...
When I share a Paper document, a list of suggested contacts always pops up. These individuals are no longer associated with my business and I would like to remove them. I can't post pictures, but here is a link to what I see. ( link removed as per Community Guidelines] I'd like to remove suggested contacts or disable the suggestions altogether. I don't know how I picked these few people to constantly follow me around. There are no third party applications or contact managers messing with my contacts.
This link from 11-11-2018 did not fix this problem...
A new feature was added last month, allowing you to clear all manually added contacts. It can be found on your Account page.
