Update 01 Oct 2020: It’s solved. The Last week of September Data may not be complete but should be in the next few days.
Photos data issues across all Google My Business listings in many categories and countries.
When you go to “Insights” to check the Photos data (Photo views and Photo quantity) you will see either blank with the message “Not enough data for selected time period” or you will see a drop in views to 0 from the beginning of September.
Hopefully, this will issue will be sorted soon and all data comes back to the profiles from the 1st of September.
Be Remarkable!
