Hi everyone, sorry for stalling this, unfortunately it seems I was mistaken and I don't think this is as in-demand as I've thought.
The Mobile IronSource Collection seems to be doing quite well already in terms of ad-revenue, and the IronSource SDK and its ad-network mediation SDK updates are quite stable for us now. Therefore, there is really little to no reason in making this yet.
I'm currently focusing on other features that are truly lacking in the collection, especially for web and desktop, including their own monetization.
Also, multiplayer/networking and documentations still need a lot more work, so I will have to focus more on those for a while.
I'll get back to this once I finish the important ones first.
I hope you understand, thank you!
