Thanks for you quick answer. I want to clarify that I would have liked to try the app for a few days before activating subscription.
Now with the current flow I would need to activate the subscription and then immediately go to Play Store settings to deactivate the subscription so that I would not forget it.
We don't discourage anyone from doing this! Free trial with access to all features stays live for the full 7 days even if you cancel immediately. Hope you enjoy it.
That's pretty standard for free trials in my experience. Amazon prime, audible, musescore, I'd be harder pressed to think of a service I've recently tried where it was not like that.
