Why is my account still not yet verified, I've been waiting for 5 days

You are showing up as verified for me:

Please try to view your verification status from an individual video. That should work, assuming no other issues.

The problem right now for you is that the URL you are viewing your channel through is https://www.youtube.com/channel/UCEx8txtvVzvyg6IFmRewPEA?view_as=subscriber, which contains ?view_as=subscriber at the end. This is a known bug which makes it so that verification status does not appear when ?view_as=subscriber is added to the end of the URL. If you remove that from the end of the URL, it should work.

When you view your verification status from an individual video rather than your channel page, it will never have ?view_as=subscriber, so you will never encounter this problem.

The fix for the ?view_as=subscriber bug has been fixed and will be released in an upcoming version of Brave.

Thanks!
