When you can’t find the option to edit vertical vs feed placement, it’s probably because Advantage+ placements are enabled. To customize per placement, you need to switch to Manual Placements and use asset customization.
How to Fix It:
- Switch to Manual Placements
- At the Ad Set level, click Placements → Show More Options → select Manual Placements (instead of auto/Advantage+).
Customize Assets
- Expand each placement (e.g., Stories, Feed).
- Click the pencil icon next to the placement and choose Crop or Customize.
Upload Proper Dimensions
- Feed: use 4:5 (1080×1350) or 1:1.
- Stories/Reels: use 9:16 (1080×1920).
Switching placements gives you full control. It’s a few extra clicks, but worth it for tailored creatives per placement.
