Should a cross-posted short keep the same caption on Shorts, TikTok, and Reels?

Asks whether short-video captions should be adapted for each destination app.

I see many cross-posted clips where the video idea is strong but the caption still sounds like it belongs to another app. Sometimes the text asks for the wrong action, sits under controls, or depends on a title field that is not visible in the feed. I prefer one master edit plus a small caption pass for each destination. Do you keep captions identical across Shorts, TikTok, and Reels, or rewrite them per app?
