I don't blame you for not remembering, but in 2024 Final Fantasy 14 Mobile was rolling out in China. Later that year, it was announced to the Final Fantasy 14 community at large, and director Naoki Yoshida billed it as a new way to experience the story and would be independently developed as a “sister title” to the main Final Fantasy 14.
Bold promises were floating around regarding content updates, and for a while, the game was getting new additions like hairstyles and mounts that, admittedly, made my regular FF14 playing self a little jealous. However, fast-forward more than a year after the game's proper release in China, and Square Enix seems to have abandoned the title entirely.
Final Fantasy 14 Mobile seems to have been abandoned
It has been reported a few times since its official release in China that Final Fantasy 14 Mobile isn't doing too well. Not only was it full of predatory monetization methods, but it also failed in its attempts to part with players with their cash. It's last major update was last November, and it has been radio silent.

Yoshi-P isn't retiring anytime soon, and he still has “a lot of game ideas in store”
His career doesn't seem to be ending anytime soon.
Final Fantasy 14 Mobile seems increasingly likely to get a global rollout, and a new discovery confirms that Square Enix has given up on the game for dead. Spotted and shared by a Reddit user called Aqualenne, it appears that the official mobile site for the game has been down for over a week. Clicking the link will take you to the error page.
With no updates in sight, disappointing revenue, and a mobile site that's been down for weeks, Final Fantasy 14 Mobile is practically dead at this point. We'll likely see unique items and hairstyles make their way into the main game over the next year or so, and I wouldn't be surprised if it was quietly shut down without an announcement. It was an interesting experiment, but seems to have failed.
