I answer the question:
"Could you check if you're still facing a lot of ANR's when you have the up-to-date versions of Unity and Firebase SDK to build your app?"
I updated Unity to version 2019.2, but the problem with ANR still remained.
The only thing I can give you is the logs from the Google Play Console.
