Mopub with Admob is very common combination for ad serving.
I am thinking to show the google consent dialog (Admob + Mopub), then grant/revoke mopub consent base on the user decision.
But I found out in Publisher-owned Consent - Disclaimer (Only specific (managed) publishers who have been given permission are able to use their own consent dialog. If you attempt to use the API without approval, we will not collecting personal data even for users that have provided consent. Please contact your account manager for further assistance.). So, I don;t know whether this approach is accepted or not.
Can someone in MoPub team stand out to give us some advice?
