Error in Ad Testing App: Creative is not compliant to any MRAID version

Hi everyone. I want to port an existing Playable Ad (AppLovin/MRAID 2.0 integration) to UnityAds and made some Adjustments (switched from mraid.openStoreUrl to mraid.open(storeUrl) etc.). If I test my Creative in the Ad Testing app I get the following report (see attached file). Now i am curios if it’s even possible to use a plain JS Playable for UnityAds or if the UnityAds SDK is required for the communication between the Ad Container and the Ad itself.

thanks in advance

@robert_unity552 ,

I’m not as familiar with the advertising side of things, but we do have our requirements listed here:
