Ashley has said many, many times already that C2 is now in 'maintenance' mode, which basically means no new updates, but still supported for bug fixing.
This is not understandable.
Unfortunately the C2 admob plugin uses the third party cordova-plugin-ad-admob component, which isn't maintained by us. As far I'm aware the plugin itself has been broken by the maintainer and they haven't looked at it for a long time. So I wouldn't hold up much hope of it being updated to include the user consent dialog.
You know it is broken, no maintained.
You making your own plugin and we need talk for this with 3rd persons. Nvm, I can make it with my own way. No need 3rd persons...
