Google Analytics linking could not be created?

Hello,

I’ve tried to create a new Analytics ID (in AdMob) for one of my apps and I got this message: View image: Capture

However, I was able to create “manually” a new ID in Google Analytics, but if I try to link it with my app in AdMob, I still get the message that’s posted in the above picture.

Does anyone know how to solve this?

Thanks.

I wrote directly to Google, but I didn’t get a reply from them yet. :-/ Anyone else, please?
