The software engineers have destroyed this product. On my MacBook Pro 2017 the software uses a huge amount of resources on startup and at random times. Status icons slow to update in Finder (several minutes). A reinstall of Dropbox has now created duplicate folders saying "Ignored Item Conflict"and "Selective Sync Conflict". I now have a big headache and a few days of work ahead to sort out understand this mess. The online help files are verbose and confusing if you are a software professional.
