I got an answer from Google on this:
"It’s important to us to provide merchants with helpful insights about their Business Profile’s performance on Google, and users can see a depth of insights in the Performance tab when they access their Business Profile from Search or Maps.
While we are moving away from providing Posts Insights, Business Profile users will continue to have access to a number of profile insights like profile views, number of calls, messages, bookings and others.
If you have further questions or need help with other issues, please visit our Help Center or contact support.
Thank you for your understanding and patience."
