Would like this as well! I spent many hours to identify an error WordPress was throwing publicly and narrowed it down to the Page Views module of Powerkit. It looks like it doesn’t support GA4. Would love an update for this soon as well.
Thanks for sharing your troubleshooting journey! Based on the symptoms, I believe I have the same issue as you. However, I’m unsure of 1) how to implement your solution, and 2) why this is an issue in the first place.
Can you share at least high-level instructions? I appreciate it!
