Issue affecting SKAdNetwork for iOS 16.1 users
Apple indicated that there is an issue affecting “SKAdNetwork” for iOS 16.1 users, stressing that it is working to solve this problem quickly in the software update.
SKAdNetwork enables advertisers to measure ad success by assigning app installs to specific ad campaigns, in other words, it lets advertisers see how successful an ad is in getting users to download an app from the App Store.
iOS 16.1 was released two weeks ago with SKAdNetwork 4.0, which provides more performance insights for advertisers, adds support for web ads, and includes other improvements.
