When setting up the campaign it is worth to keep in mind that the more rules you add, under "Audience" and "Media" for each Bidding Plan, the inventory that the campaign is able to access will decrease. This will then limit your possibility of doing optimizations. And for doing optimizations it is best practice to be able to access as much of the available inventory as possible and to have as many formats as possible.
