### 1/5 — Broken

*2026-02-17*

I have the latest M5, 13” IPad Pro. Yet, the app states that it is not capable of Apple Intelligence features. I have AP set up and its features work fine with other apps.

**Developer response:** Hi there, thanks for your comment. This has been fixed in the recent update.
