Not showing on Opera.

For some reason the plugin works fine on my site when using Firefox and Chrome but on Opera (on the desktop; on android it’s fine) the popups don’t show. Not sure if this is a default setting in Opera (including when Adblock isn’t set for that site).

Is this something others have come across? Not sure why…
