Hi. Sorry you’re experiencing this.
I wasn’t able to reproduce the issue using Chrome’s responsive/device emulator for Nexus 5, but it appears your theme or another plugin is implementing custom scrolling (what’s sometimes referred to as “scrolljacking”)
Therefore, since this likely isn’t an issue caused by our plugin (since we don’t implement any custom scrolling), I’d suggest switching to a WordPress default theme like Twenty Fifteen, Twenty Sixteen, Twenty Seventeen, etc. and see if the issue is no longer there. If this is the case, I’d recommend asking your theme developer about this issue.
