Some of the reason, our apps still use WKWebView to call Urchin WebAnalytics Software(Urchin/graylog) like Google analyzes traffic to record page view and user(first-time visitor / existing visitor).
Before 12th Sep 2022, software still in function.
After 12th Sep 2022, our team found that the software report field "first-time visitor" value is abnormal, a huge increase to about 200% every month. But other fileds are still good.
I guess that it may be some behavior like cookies has been changed on iOS16 client side, but i am not good at networking. Does anyone know what happened in this case and how to solve.
Many many thanks
