Carousel ads no longer compatible with some Engagement campaigns?

I’ve historically liked to use carousel in Engagement - specifically ‘post engagement’ campaigns. My team recommended a carousel asset be rotated into a campaign with this objective only to find carousels are no longer available, only image or video.

Am I just out of the loop here or is this a new limitation? Not for nothing, it’s a silly limitation imo- why dictate the types of ads that can drive post engagements?

I also can’t change the objective of the campaign; this is for a large client within an agency wherein plan details are ironed out and approved pretty far in advance. (And obvs I asked our Meta rep about this; waiting to hear back and wanted to get a feel from other folks who are hands on in the platform.)
