As far as i know your watch history overrode any start time you defined for your embedded video, even if you put in a specific start time. Now, it seems that even without a start time the video always starts at the beginning, disregarding any watch history.
Is this as intended? Is this even happening for anyone else? Is there any way to still start at the watch history?
I checked both the iframe api as well as a regular embed and it seems both ignore the watch history.
