Thanks for your reply.
I have read those docs several times, and that is not the point. Please let me try to clarify.
Bottom line is: On a unity project, adding the package GoogleMobileAdsInMobiMediation.unitypackage makes the app ask for the following permissions: Phone and Storage
The 2 documentation pages you are sending me to are not related, they advise to add optional permissions. I did so, just to test, and unsurprisingly the app requests for the additional permissions: Phone Storage, Calendar and Location.
Which does not solve my issue: why adding GoogleMobileAdsInMobiMediation.unitypackage alone makes my app request for Phone and Storage permissions?
Thanks in advance
