Hey Zx6ruedy,
We understand you'd like to find out why you're not seeing any data in your privacy report for Safari on your iPhone. We'd be happy to help out.
To get started, you'll need to make sure that "Prevent Cross-Site Tracking" is enabled for use under Settings > Safari. Once ensuring this is enabled, check to see if the issue persists. If it's already enabled and the issue persists, do you notice the same behavior with all sites you visit and on multiple network connections? We see that you're currently on cellular, does the same behavior occur over Wi-Fi?
For more info on using the built-in security and privacy protections on your iPhone, check out these resources:

We hope this information helps out.
Take care!
