Google Tag Manager - Problem connecting to GTM

Hi everyone,

I´m developing analytics on my mobile app using Ionic 3.20.1 and I am having too many problems with the connection to Google Analytics.

I can reach my Firebase project and watch my hits on the debugview. On the other hand, I cannot reach Google Analytics. I checked that hits don´t get Google Analytics RealTime view.

I followed the steps explained in https://ionicframework.com/docs/native/firebase

Do you know how to fix this problem?

Otherwise I tried to search the GTM container in the logcat console but I don´t see it. Do you know if I should find it there? How could I solve it?

Thank you in advance.

This is my package.json
