Are you inserting a general activity, or a task in a tasklist?
We’re currently using 4.0.249.89 (and previous versions) and it’s been working consistently as far as we’re aware. Better get this working because placed-file support is on the way too
seems to be working now. Strange. The only thing that gets put at the top now is the Scheduled Email, which I think should be at the top since it’s a future activity: you don’t want something to change in the project/contact and then forget to change the schedule email. When I was trying it before maybe I was only trying schedule emails and upload a file, so no wonder it wasn’t working
