I have a MacBook Air M2 (MBA) running Ventura. I previously installed Dropbox (DB) on that computer but had to stop syncing because I wanted to run it on 3 other devices.
When using my MBA again, I launched DB. I had to unselect one of my other DB devices. When DB began, I thought it was verifying my files to match them with the version since my last connection. In fact, I later realized that it renamed my previous DB folder already in the ~Library/CloudStorage folder, created a new one and synced my files all over again.
When that came to a completion, I could see a DB alias folder in the root of my user folder pointing to the new DB folder location just beside my previous one.
I really don't understand why DB did not simply synced my previous DB folder with the cloud version instead of creating a new one all over again. My only possible clue is that when the original DB folder was created and updated to work with OS 12.5 and earlier, I trashed the alias folder that DB created in the root of my user folder, folder that has been created again with this new installation.
What am I missing or what have I done wrong ?
