4. Yes, a single Cloud account can be used for Cloud
sync.
5. No.
Thanks, Nick, for clarification. When writing 'No' I meant MLO Desktop app or MLO iOS/Android app registered under single user license.
But Nick is right, using different devices and Cloud sync more than 1 person can enter information on MLO at the same time.
One caveat, don't try to edit the same task on more than one device as you'll get sync conflict and lose one set of changes.
