I have the same issue.  The cloud shows that I have successfully backed up 2282 messages and 517 call logs, but It does not display any of them on the phone and I can't figure out how to look at them on computer either.  How do you browse thru the the messages and call logs you have backed up.  Also, how do you delete them if you no longer want them saved on the cloud.  This feature is also not on the phone app.   thanks!
