@Marie , @Nao_Kumazaki , there is an existing topic which is closed that I think we should reopen and merge the above thread into it. This issue has not been entirely addressed and so I don’t think it should have been closed. (I tried opening the existing topic but it would not let me for some reason 
)
A rule adding a task from a form to a section works fine, but the issue is that all tasks ‘land’ in the first section before being moved to other sections by such a rule. The issue happens when the first section has any rules - these will fire first at the same time as moving the task to the designated section, thus the workaround above, which is clearly not ideal.
The ideal would be for the form’s settings to have the ability to choose the section of the project that the tasks will land in, similarly how you can set a designated assignee in the form’s settings.
