But we have seen this practically many times that the assignee of a campaign can only submit content. Please note that submitting the content is different than approving it.
The Approval lifecycle goes like this : The campaign assignee (manager) submits the content and then it becomes active for the approval process and content and targeting can be approved then. By default only the assignee of the campaign is allowed to submit content and not the selected approvers for the campaign.
Thanks, Adhiyan, Yes it is assigned to admin but why would this cause any problem in the first place? Some explanation or product limitation available to support, I can't just ask them to do it without any explanation.
