Mr. Musk may have successfully pushed Twitter's new name and logo, 'X', and even made the vanity domain x.com redirect to the social media website, but that's not to say, the Mathematical double-struck letter will fit the bill everywhere. Apple's App Store can't accept Twitter iOS app's new name due to minimum character requirements
If they wanted too they’d just do what everyone else is doing on the app store and call it “X - Social Media” or “X - WHAT’S HAPPENING”
I feel like he’d try and pull a lame meme name change if forced. “XXX” is immature enough for him to try I bet lol.
