ARGB Help?

[Hman1250]

I recently built a new PC and I’m currently trying to get all my parts to sync together. I built inside of a Lian Li LANCOOL 215, with an Asus ROG STRIX B550-F motherboard, a hyper 212 black RGB and a Corsair CX650F power supply. All these parts support Asus Aura Sync. My 212 RGB syncs perfectly fine as it’s directly connected to the motherboard with the 12V RGB header. The motherboard has one ARGB header, and the case has a fan header, connecting up to 5 fans, and 4 ARGB devices (3 with one splitter for expansion). The header then has one cable that connects directly to an ARGB header, in which I have connected. However with all devices connected to the hub, armoury crate does not sync the other devices with the motherboard. The case says to hold down the LED button for 3 seconds and it will sync, in which i have. Any reason why this is happening?
