The Amazon Mobile Ad Network (AMAN) now offers compatibility with iOS ATS. Starting in 2017, apps submitted to iTunes are required to connect to web services using the App Transport Security (ATS). When ATS is enabled, apps make network calls over a secure HTTPS connection.
If you are preparing to submit a new app or an app update to iTunes in 2017, make sure you are using the SDK v2.2.15. If you are not yet preparing to submit a new app or an app update in 2017, you can continue monetizing with your current SDK.
If you have any additional questions, please submit your inquiry through the "Contact Us" in your Developer Portal.
Best Regards, Amazon Mobile Ads Team
