On Monday, it appears X attempted to encourage users to cease referring to it as Twitter and instead adopt the name X. Some users began noticing that posts viewed via X for iOS were changing any references of “Twitter.com” to “X.com” automatically.

If a user typed in “Twitter.com,” they would see “Twitter.com” as they typed it before hitting “Post.” But, after submitting, the platform would show “X.com” in its place on the X for iOS app, without the user’s permission, for everyone viewing the post.

And shortly after this revelation, it became clear that there was another big issue: X was changing anything ending in “Twitter.com” to “X.com.”
