We have run into problems with the Mobile App when creating a task in calendar view, where members have clicked on a day to create a task, built out the task with a name and details only to have it disappear later.
We discovered its because when they click on a date to create a task, Asana does not automatically fill in the due date field for that day. So when they save the task with no due date as a result it does not appear in the calendar (only in alternate views).
It would solve a lot of communication breakdowns if this feature can be created.
Let me know if any other information is needed!
