PM practices/tips for using Asana to manage Marketing

Hi! I recently joined a company (150 people) as their first Project Manager and looking for tips/best practices to use Asana to manage multiple marketing teams and the creatives. I came from a place that used Trello and understand Asana’s features, but am looking for advice on how to best manage multiple teams with intersecting priorities, have visibility of the current workload and set up routines so everyone is using Asana the same way… it’s a bit of a mess and each person/team uses the platform differently if at all.
