Since it was never announced on the forum, here’s a thread for our official Applovin extension for Defold!
It includes support for interstitial, rewarded, banner, and MREC ads, along with MAX debugging, consent, test-device, custom-event, and revenue APIs. Read more details in the documentation.
We’re also glad to announce the AppLovin extension for Defold has been updated to 2.0.0! 
This major update brings the extension to AppLovin MAX 13.6.3 and supports Defold projects on Android and iOS.
Please note that version 2.0.0 requires Defold 1.13.0 or newer, Android API 24+, and iOS 15.0+.
