I have a m1 mac and longstanding free dropbox account and noticed almost all my local files were gone. It looks to me like some update to the desktop app seemingly turned on selective sync (ugh) and now all my files are online only.
I'd like to set it back to local files present 'and' synched to online as it has been for many years.
I found and (re)set the sync=>default sync state for new files to 'available offline' but do not see a way to tell it to catch up that setting for existing files already moved online-only. There is no 'sync back the other way FROM dropbox' option that I can tell.
Again, I want local copies of everything, and online copies sync'd copies of those.
I am very reluctant to try SelectiveSync unselect all -> update -> select all -> update or something like that. I also don't want to use the 'download' option to grab a second copy of many GB of data. I just want the app to resync and get local copies again like I had it from the earliest days of dropbox even existing.
How do I do that without risking losing my data ? Right now I think I'm in a position where a dropbox server disk crash loses everything. That would be bad.
