You may not be a fan, but the X re-brand is here to stay, which likely means that you’ll need to update your website, your in-store signage, staff email signatures, and other promotional material with the new X logo.

This might help. X has updated their brand asset resource with the new branding, which Elon Musk said was an interim solution, but he seems to have settled on now.

So it should be fine to update to these new icons. Should be.
Interesting to note that X hasn’t updated the wording, so you’ve got the old: “Our logo is our most recognizable asset” description on the first example. Which is likely no longer true, as most people have no clue what the X is. But Elon seems confident that they soon will, and that the Twitter bird will be forgotten, as X becomes the place to share all the latest updates and happenings.

But it will take some time.

The Twitter logo is arguably one of the most recognizable brand icons in the world; but despite the long-held vision Musk has for his X concept, changing the app's branding was somehow done on a whim, with a user eventually submitting the design for the new X logo.

That seems a bit too hasty, eroding decades of brand equity. But Elon is confident in his "everything app" vision, which will eventually make the X symbol of the most valuable brand on Earth. In his words.

This will take some time, but if you want to move on to the next level, you can now check-in on X's brand assets to ensure you're using the right icons for your links.
