Hi there,
Thanks for relaying your feedback!
Did you run into any specific problems when mediating using other ads APIs? It should not be complicated to set up, provided you walk through the correct sequence of steps as outlined by the mediation partners. Let us know if there was any issue at this stage, and we will be happy to assist.
As far as SDK-less mediation goes, we don't really have visibility into how others structure their logic. But again if you have questions in setting things up, feel free to let us know.
