Changing Report Schedule - maintain notifications
Analytics Configuration and Subscription - when you change the schedule of a report, it wipes out the email notifications that were set up in the original report. This should not happen - these should be maintained. We did not realize this until we did not receive a report we were expecting and we tracked it down to this issue.

I wonder if this is a local / environment bug? I have changed Analytics Object List scheduling many times and have had no loss of notifications in Manage Subscriptions.
