How do I A/B an Instagram Reel?

On one Library clip, publish Instagram with Reels + Trial. That posts a Reel and a Trial Reel. Compare views on that clip’s Details page after Insights refresh.

1. Open Library and select the clip.
2. Set Publish to an Instagram account.
3. Click Reels + Trial, next to Publish. Confirm in the dialog.
4. Studio posts the Reel, then queues a Trial Reel of the same clip.
5. Open that clip’s Details page. Under Performance, Insights shows Instagram reel views and trial views after it refreshes.
6. On Scheduling, include Instagram and tap Reels + Trial before you save. Track the same Reel vs Trial numbers on video detail, not on the schedule.
