I have built a page on this template and I am not sure, if it's a template or module issue. This is the observation:
I am using the built-in cookie consent of this template. No matter if explicit or implicit, if I open the page on a mobile browser (Chrome and Tuga tested) the content of the website gets shown a tiny moment before the page turns grey and only the cookie consent overlay is visible. It only loads when I click on that overlay.
I have created a video which shows the behaviour. It's edited a bit for privacy reasons: http://sendvid.com/c75f1xfe
On a browser everything is working fine, also when I request the desktop version in chrome it suddenly works. Could some CSS prevent the content from being shown?
