App not working in IOS 15

Hi all,
I’ve created a lots of build with “expo build”, that builds not working with ios 15 (all fine with previous ios version), my expo sdk version is 43, why this happen? The sdk 43 officially support ios 15, but still the app not working properly (lots of issue: component not updated, toast non hidden after timeout, button not pressable, …).

I need to switch to eas build to support ios 15?
