Strange Rhythmic Noise on iOS

[billyking991]

I'm mediating using MoPub. When I updated the AppLovin SDK from 6.10.1 to 6.12.6, as specified in the MoPub mediation documentation, users started reporting a quiet rhythmic shhhing sound at approximately 1/2 second intervals. The sound is affecting the ringer/alert volume and disappears when the device is muted.

The sound happens when the AppLovin SDK is installed in the project even if the SDK isn't initialized. As soon as I remove the SDK the sound disappears.

I know it's the AppLovin SDK because I systematically turn off each SDK until the sound stopped.

Last Version Installed: 6.10.1 - No sound.
Current Version Installed: 6.12.6 - Rhythmic Shhhing sound.
iOS Version: iOS 13.5.1
MoPub Version: 5.12.1

Please let me know if you need any info from me.

Hi @billyking991,

Could you update to the latest AppLovin iOS SDK, v6.12.8 (pod 'MoPub-Applovin-Adapters', '6.12.8.1')? This was fixed in a subsequent release, v6.12.7.
