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.

The app not working, i just wanted to do an A/B test for shipping rate. The exchanges with support lasted four days. First, they asked me for an authentication code to access my store (which was strange), then they told me it was fixed but it still didn't work, and then they asked me to call them to fix it live, even though it had already been done normally. In conclusion, four days wasted for…
Very bad, I insist for a long time, has experienced constant error, delay, unable to create the test, can't choose the product after test finally launched the first product price, but it's very wonderful is a few hours later I products in the price of shopify concrete was somehow changed, changed to test the price of group B, ridiculous! Customer support is slow to respond, I can never reach…
Doesn't work very well, when you've created a price testing sometimes the test just disappears, you cant edit it either.
