As of today Twitter has officially moved to the x.com url:
Currently upon putting x.com as your profile link it says The url must match the social media type.
As we can no longer use the twitter.com url as it simply redirects, it needs to be updated to x.com 
We should be able to use both twitter.com and x.com for the sake of backwards compatibility. not replacing one with the other
Agreed, it needs both
I can see twitter.com going in the future, but for now yeah it needs to be added
I think they’re working on this.
Check this thread:
When I was on the thread I mentioned it, but having a look at what skpm said on the list, it doesn’t include changing the urls for us
Hi! Sorry I missed it on the other thread, that was more of a UI changes list.
The team that does the url validation is aware of the issue and we’ll update you when it’s fixed!
