Hi, there is no issue that we are aware of.
I have had a quick look at your site (assuming same site as your email domain) and I cannot see any problem with scrolling on mobile device (Android).
I’ll try to recreate the issue you are reporting. What mobile device and browser are you using when this issue occurs?
Does this problem also happen when you view our demo site?
Do you see this problem on your “live site” or is it only when in the customizer preview (or vice-versa)?
