I have a team of 4 individuals helping build my site. One person was responsible for uploading a bunch of photos. The other person was going to add them to a gallery, only to find out that they can ONLY see data THEY have uploaded. We have had to have all four of us use the same login and coordinate when we are online.
Hi there, we are working on a new Media Manager, which will be rolled out in the following months, where contributors will have access to all site media including visitor uploads (which will finally have its own dedicated section). It’s gonna be worth the wait. In the meantime, I’m afraid the best workaround is either what you guys are currently doing or manually organizing these uploads in a shared Dropbox/Drive folder. All the best.
