I'm using Corona 2017.3184 and building for Android. In the process of testing on iOS.
Within the Unity Ads dashboard there is an option to allow skippable interstitials, eg 'Skip after 5 seconds'. However, this setting is ignored on the device and the full ad plays out - 25 seconds or more.
We're considering migrating to Unity Ads since they seem to have the best strategy for dealing with GDPR, however unskippable ads would definitely have a negative impact on our app's users since current ads (AdMob) are skippable.
Is this a bug, or is this feature unsupported in Corona?
