The most common GemX complaint: support
Tracking is inaccurate even after 24 hours. The app doesn't collect data on orders or visitors at all. I wasted two days testing only to see results that make no sense and don't match reality. Support doesn't exist. The support app itself doesn't even work. No way to get help, no responses, nothing. Stay away from this app.
