Instagram and FB videos only play on wifi

[AC Question]

My facebook and instagram videos only play when I'm connected to wifi, when on cellular data they just try to load but nothing, browser and youtube videos play fine, and the browsing speed on cellular is fine, even facebook and instagram work normally , just will not play videos, as soon as I switch to wifi they work , tryed resseting the data settings, reinstaling both fb and insta, and nothing changed

I would do a Factory data reset.
