I need a developer who can reproduce and eliminate a freezing issue on the web form hosted at https://formsigny.com/new/pdfj/. What’s happening • When the page is opened on an iPhone, the interface becomes unresponsive after a few minutes of normal use. • The issue appears only on iOS devices; Android and desktop browsers work fine. Your mission 1. Open the link on an actual iPhone, interact with every field, and keep it active for at least five minutes to observe the freeze. 2. Trace the root cause—whether it’s JavaScript, CSS, or a WebKit‐specific quirk. 3. Implement a clean, maintainable fix without breaking existing functionality. 4. Re-test on multiple iOS versions (Safari and, if possible, Chrome on iOS) to confirm stability. 5. Provide a brief report outlining the problem, the steps you took, and the final solution. Experience with Safari remote debugging, WebKit inspector, and performance profiling will be valuable. If you can stop the freeze and verify smooth interaction, let me know how soon you can start and your estimated timeline for delivery.
