Yes, to generate working player with active onclick event you need to execute ly.te() once again when popup is opened (when its content is already visible).
It’s internal project but today I’ll try to clone problematic section somehow.
Frank, that’s right, exactly.
Btw: I think “Visual Event” plugin would be helpful in diagnosis of this case.
To decrease loading time and reduce number of requests I recommend Gonzales plugin. It conditionally removes useless CSS/JS so after proper configuration overall page size will be more lightweight and faster.
First of all you should think whether you need these CSS/JS or not. if you think they are useless you can dequeue them in function file or use Gonzales pluginin case you don’t feel certain in modifying PHP files.
