Sorry. I only test my lulz-ware in android chrome.
I have fun and then wanna show people my toys so they can play with them.
What do you mean by embedded browser?
From your message its hard to figure out os, browser, versions, device or really anything.
"It works in chrome" :-)
I get an install process going in both android and ubuntu.
Btw. Have you checked my code on creating the charts? I really had fun making them without libs/etc. Its just svg with some translateX stuff hehe
Perhaps some device detection improvements are warranted
