Particularly, i have the error in arabianporn.site , it other websites i can run with jw player, but as i changed the iframe to amp-iframe (this is why there is a placeholder image), i had to remove the moz, webkit… so with js player it misses many elements and i have to use js player. This is why i discovered that this website does not work with jw player.
By the way, i already run videos with AMP and no errors since this afternoon, i already have 3 websites working perfectly plus this one that has this error. And i have 9 left to install. I have to wait google to index them, last week, it indexed the pages after 2 dais or so, multiplied traffic by 50% and then, found the errors, and deindexed them from AMP.
