So when I go on Facebook (whether it's on the laptop or phone, website or app) the images and media will take really long to load, when I am connected to my APs. However, when I connect to my router's WiFi everything loads fine on Facebook. On the APs I can access everything else really fast, only Facebook images won't load fast. It seems very weird. 

I have a UniFi UAP-AC-EDU and a Cambium E400 AP. I set up two different SSIDs (three if including the router's built in one) to test them out and both the APs would load every other site fast and just fine, however the Facebook website and apps would load the images really slow.

Has anybody come across a problem like this before?
