I ... don't think there's a time limit on TikToks unless you mean that 60 minutes is a time limit. Are you thinking of Vine?

If you want people to watch your content there's definitely a time limit. I don't mean anything imposed by the platform; I just mean if people aren't interested within 3 seconds, they're scrolling to the next video in their feed.

That's a pretty new thing though, in 2020 it was 1 min I believe, and most people skipped after 15-30s

Then it got increased to 3 min and now 10/60 min

I miss Vine
