longer youtube shorts

I've been researching it for quite a bit now, but that only adds up the doubt. I want some help with warming up the profiles to make it ready for YT. So, like - 1. Do we need to warm up the profile by surfing the web? Or should we straightaway jump to YT and watch like 30 minutes before...

I'm sure this will be of major interest for you lovely peeps: https://blog.youtube/news-and-events/tall-updates-coming-to-shorts/ "Longer Shorts, more of you. Starting on October 15, you can upload Shorts up to 3 minutes long" It seems they're working on the yt shorts algo rn:
