Analytics setting up, stuck on Play to complete integration

Using Unity 2021.1.11f1 on Linux 20.04.
When setting up Analytics, I get stuck in the "Play to complete integration" step:



After 30 min of playing, the configuration still in this screen and doesn't seems to do anything. Do I have to wait more??

Also, another strange thing is that, some times, pressing the play button creates a current session in my Dashboard:



Assuming the integration have been done, how do I access the Analytics Monobehaviours?

 

The message in the Editor is a bit confusing, it will be removed in a future release. You are properly integrated with Analytics. You can call Custom Events using this code, you can import the Analytics Library from Package Manager

As usual JeffDUnity3D, I appreciate that you respond so quickly. Thanks!
