Hello, I have had dropbox for several years, but was inactive for many of those years. I made sure I had copies of everything and deleted what was in my account (it wasn't much). I am now on a team for work where we use Dropbox to upload files to a shared folder. Whenever I try to login, or am given a link to upload a file to the folder by a coworker, Dropbox says I'm out of storage and asks me to upgrade. I'm super confused and frustrated. What is happening and how can I fix this so I can access the folder?
