3. Tap "View Profile" if needed.
4. Scroll down and tap the "Contact Info" section.
5. Your public profile URL will be displayed there, usually starting with www.linkedin.com/in/.
6. Tap and hold the URL to copy it, or use the "Share" or "Copy link" option often found by tapping the three dots (More) icon near the profile sections.
