Hello! Due to the recent youtube changes, both our website and the add-on are enable to download in 720p. We are trying to bypass it, but with no luck yet. For now, we can recommend switching to Televzr app, that can download in 720p and higher:https://desktop.televzr.com/#
I've noticed the same thing too. Is there any way this can be fixed?
