YouTube Profile URL

Just created an account and attempting to add my profile URL in the format requested (youtube.com/c/profilename) but the new YouTube profile format requires an “@” in the profile URL which is stripped from the format whenever I try to inputting the valid YouTube profile, leading to a consistent 404 message when trying to click YouTube from my nomads.com profile

Specific examples

What my valid YouTube profile is (from YouTube profile channel URL field) - https://www.youtube.com/@abusyhippie

What nomads.com keeps reformatting it to -

https://youtube.com/c/abusyhippie (this gives a 404 because it's missing the “@”)

I've also tried adding the nomads.com format with “@” but it still gets stripped and 404s
