User Profile

I have implemented Text on camera feature in two ways UITextField with UITextContentType and UIKeyboardType as emailAddress, which helps to show a button in the keyboard to open the camera for capturing email. UITextField with basic text. I implemented a custom UIButton to open the camera for capturing text for this field. In both cases I'm not getting callback in any of these functions insertText(_ text) setMarkedText(markedText:, selectedRange:) and unmarkText() after user taps Insert Text button. Help me.

I have read the Prepare your Network for iCloud Private Relay. In that I have two queries, We use IP address to limit usage of our app to prevent fraudulent. The video says that more than one user in a city uses the same IP address, so there will be more network calls from same IP. How do I adapt private relay to achieve this case? We show to the user that from which IP address his details are created or updated. Since the IP we get from the Egress proxy is modified, we cannot show the correct IP to the user from which his details are created or updated. And how to solve this after adapting iCloud Private Relay? And also I like to know how broader the IP will be modified from the users' location? I cannot find any document regarding this.
