Android 9 strange behaviour after app installation

Multi tool use

I have a strange behaviour with Android 9, on launching the app for first time after installing from Play Store. On launching the app second time, the issue just disappear.



So, there are 2 issues, which can alternate, but they are always there:



1- the cookie manager is not able to read all cookies from a WebView. I have already posted a question on this subject here: xamarin android 9 cookies read issue



2- Firebase returns a blank notification token, even if the authorization token is valid and the google-service.json are good. In fact, in android 7 and 8 the firebase notification token is alway right.



To my test I use a Google Pixel 2 XL and I use the Xamarin framework.
