David, i finally fixed the annoying problem π
2 plugins: Perfmatters and WP-rocket. “Disable Embeds” was active, that was the reason of the ugly white space. I disabled it in the settings and the video’s are now embed and responsive!
Thanks for the support! Is it possible that you add this to the tutorial of generatepress, i think others will make the same problem as i did.
Anyway thank you very much π
