Even getting ahold of their support team is not guarantee of help.
I have a professional Dropbox account, and have for years.
I have 4 computers all running Dropbox on an external drive (because the internal drive doesn’t have enough space for my entire Dropbox).
ONE of those computers has regularly had an issue where it says that it is syncing 10,000+ files, even when it should be idle. It stays this way for days.
Their support has given me every reason du jour from “Are you using symlinks?” to “Are you on the beta?” (sometimes their answer is to use the beta and sometimes their answer is to avoid the beta) and (my personal favorite) “You have too many files in your Dropbox folder” (even though I was only using 1TB of my 2TB account).
Recently I was trying to diagnose this problem again and their tech support person wanted me to use the “Fix Permissions” feature — which has not actually been in the app for several years.
When I explained that I had done the steps necessary to fix permissions manually via Terminal (as they had posted on their website), they happened to notice that my Dropbox was on an external drive.
“We don’t support Dropbox if it isn’t installed on your internal drive,” they said.
I explained that it had been like that for years, and it is working fine on several other machines.
“We don’t support Dropbox if it isn’t installed on your internal drive,” they said.
I asked them how many computers they know of these days that have 2TB of internal storage.
“We don’t support Dropbox if it isn’t installed on your internal drive,” they said.
Eventually I just gave up. If it happens, it happens and I just ignore it.
