This seems pretty cool, but whenever I try to visit this promotion page (using my cellphone with google chrome) I get an error and it just sends me to the homepage… Will try tomorrow using a desktop computer but just wondering if anyone else is having the same problem?
Tried to replicate your situation [accessing through mobile with chrome] and I can access them just fine. I didn't submit the form and accessing through incognito, though. Try to do it through incognito or clear your cache, perhaps? Or maybe enable the "desktop site" [through the kebab menu, that three vertival dots], see if it helps?
