Search bar in app

Hello

I'm a PRO user and I use musescore on my iPad and on my computer. I can't access the same scores from the two different devices when I search them. For example I tried to search "in your own sweet way" from the computer and I can read the official scores and many others. On the iPad, with the same search filters I find only one score, and the others are about different songs. It seems also that official scores doesn't appear on the mobile apps. Why??
