I create a new item in INBOX.
At the New Item screen I write a TITLE, set a DUE DATE and I choose SCHEDULED as the new item list. I don’t set any TAGS, PARENT, TIME or ENERGY.
I press the validation mark and the action “dissapears”. There is no way to retrieve or list that note until DUE DATE arrives.
This happens in Android, not in Windows desktop version. In the Windows version it forces you to choose either a START DATE or make it RECURRENT when you are placing a new item in the SCHEDULED list.
