Is it necessary to apply on the university portal as well when applying for a CSC scholarship Type B?

[DarkestLight]

I applied for a type B scholarship on the CSC website a few days ago and just today my status changed from "submitted" to "in progress". However, I checked other peoples experiences and saw almost everyone also submitted an application on the university portal.

My main issue is that even though the university I applied to has a website as well as instructions on applying to online portal, there's no proper link to the portal. The only available link is for 2022 applications and shows up with the "powered by CUCAS" at the bottom of the page and doesn't show my program that I applied for at the CSC portal. 

I'm confused now. Why would CSC show a program for my preferred university if it's not on their official portal or is the portal no longer available?

The rule for applying on both portals was also published in an article on their website in 2022. My guess is that there's no update since then because it's no longer required and also because they've already changed my status to "in progress" but I'm not sure.

Please share your thoughts and experiences.
