myTracker: iOS 14.5+ & IDFA benchmark on May 31
Numbers are no good for any UA manager.
16,9% of users have updated their devices to iOS 14.5 or higher as of May 31.
The maximum opt-in rate for games is 33%. The lowest one - 9%. That means that in an ideal world you’ll be able to reach only 33% of the audience you were able to reach before (from those, who are using iOS 14.5+).
