Dropbox Stopped Syncing Since the Update?


My Dropbox stuck syncing for 4 months, please help!

Ever since Dropbox released its new update, my files have been stuck on the same few hundred files, and haven't been able to sync or save anything new in over 4 months. All the while they keep charging me my monthly fee. I've reached out to support several times and none of the solutions have helped.

I've unlinked and relinked my account, and have used their terminal commands, which were also to no avail. I'm using an external drive for my dropbox folder, it's not a network drive. It has worked flawlessly via this setup for over 10 years. Now with all these new updates etc, Dropbox no longer works as it did. Anyone can help me?
