I connected my two Macbook Pros to the same SipderOak icloud account with the expectation that if I updated a file (one of those I initially uploaded to SpiderOak) on one laptop that it would automatically be uploaded to spideroak and then when I turned on the other laptop that updated file would download to the 2nd laptop. But it don't seem to work that way. Is there an icloud system that does work that way?
