For those of us using the CloudStore and a proxy workflow with Dropbox or Google Drive, there seems to be an issue where if you connect to your synced proxy footage (i.e. you take your laptop home and reconnect the proxy to the dropbox source instead of the CloudStore proxy source), you can't connect back to the originals on the CloudStore once you are reconnected. No manner of unlink/relink, removing proxies, changing source folder or updating Path Mapping will help. You can literally tell it to change the path, and it just ignores you. If you listen closely, you can hear the engineers laughing at you.
A solution was posted here

CHANGE THE ORIGINAL FOLDER NAME.Then, relink of course.
If the file path won't update when you tell Resolve to Change Source Folder, then change the name of your source folder. My folder names all end with a YYYYMMDD of when it was created, so I just added "-01" to the end, then changed source folder, and it worked.
I hope this helps someone else out there.
UPDATENaturally shortly after posting this, my own solution didn't work for me. Then I found this solution below, which did:
