I use Dropbox for web storage. [I do not have and DO NOT WANT the Dropbox desktop app; it pretty much destroyed my computer by hiding all my files in the Library, and I'm still trying to recover from that. So, I do not have a Dropbox icon in my menu bar or in my Applications folder and cannot tell you what version I'm using -- if there IS a version to the web-storage-only Dropbox.]
I have a Dropbox personal account with 2 TB of storage.
That said, I have a Dropbox folder in Finder in my User on my 2023 M2 MacBook Pro. It is not synced with my Dropbox.com account. There are both folders and "loose" files (files that are not in folders) that show up in my Dropbox folder in my computer but are not present in my Dropbox.com web view.
Contrary-wise, there are files that my husband has shared with me from his Dropbox account that show up in my Dropbox.com web view but not in the Dropbox folder in my computer.
This is all one account. How can I get the online Dropbox and the Dropbox folder in my computer to synchronize with one another??
