How to change AdMob's AdSense Account

[Pedro Lopes]

I will try to resume this question here:

 - On google account A, I upgraded AdMob (to monetise Android apps), which in turn associated to AdSense from that same google account

 - On google account B, I already have an AdSense account, which I use to monetise YouTube videos

What I would like to do is associate account's A AdMob to account's B AdSense.

I'm only only this wrangled problem because it seems that one can only have one AdSense account. (Can someone please confirm this as well?)

Thank you!
