In-app consent is no longer a banner you add after the mediation stack is finished. Demand partners read the signal, and a missing or late signal simply removes them from the request.
What the SDK needs before the first ad request
The consent state has to exist before the first auction. If the app asks for an ad and only then asks the user, the first sessions monetize against a smaller set of partners than the rest of the day.
What publishers should confirm
Check that the choice the user made is the choice the adapter forwards, including “no” and “not yet.” A default that looks like a yes will not survive a partner audit, and it will not match the privacy choices you publish.
