Hi there, @Daniel Dymek ! Just seeing this, so sorry for the delay! But glad it is working now! For future reference, Proko uses Vimeo to host the videos on our website. Occasionally, users will have issues with the Vimeo player because of their device/browser/network. Should this happen again, troubleshoot by asking the following questions: Does this happen with all the premium videos? Does this happen with other browsers? Is your browser up to date? Do you have some kind of firewall or plugins that might block the video player?
