Q: Will Facebook IPA for iOS 9.3.5 work on all iOS devices? A: Facebook IPA for iOS 9.3.5 is specifically designed for devices running iOS 9.3.5, so make sure you're running the correct iOS version.

The IDFA changes introduced in iOS 14.5 and later versions have significant implications for Facebook and other advertisers. However, since iOS 9.3.5 does not have these changes, its impact on Facebook's advertising business is minimal. As the user base for older iOS versions decreases, Facebook and other advertisers will need to adapt to the changing landscape and focus on newer versions of the operating system.
