I’ve cleared the cache and the problem persists with my site and also with all the Cardinal demos when using Chrome for Android (version 40.0.2214.89).
However the sites are working fine with the Firefox for Android browser.
In the chrome emulator it works fine but is not the same thing has a real device.
Do you have any change to make a test or ask someone to test in a different Nexus 5?
This was fixed now by the development team. It will be available on the next theme update.
If you need it sooner please send an email using the contact form in the link below, just saying that you need the fixed version of Cardinal because you couldn’t scroll on Mobile.
