Google's Marketing Platform is no longer maintained
It seems to have been no longer maintained(Written on 2023.12.04). I've tried to delete organization from the Google's Marketing Platform (even represented as Platform Home) but failed with 200 OK response.
I'm not sure why this happens but the service is definitely slow and not working as expected.
So, I'm moving to Microsoft Clarity.
Clarity provides even heatmap for user actions. It definitely provides all the essential features and also handy, well managed.
