I was just helping a user who didn't see all his tasks on the Home view. I've checked a couple other users too, and the pattern looks like only tasks from Current projects show up in the Home view.
Can I make projects with a Planning status show up? We have a "PPS" status that equates with Planning that we use for building a business case and prepping for our initial Executive Review. There are tasks that need completed in this stage as part of building the business case. We don't make the project Current until after this initial Executive Review to differentiate approved and non-approved projects.
