You should also set PVID 20 for port 1 of switch 3 in order to reach VLAN 20 interface on the router.0

Hi @Domdas,
Welcome to Zyxel community!
According to your description, i draw a topology below, could you check if my topology is same as yours?
If yes, could you do a test is that try to sequentially ping Switch 3, 1 from client and share us the result?
By the way, kindly ask what device is port 6 switch 1 connect to?0 -
Hi @Domdas,
I would like to notice VLAN trunking in GS1900 is different to GS1920.
You need to enable VLAN trunking on port LAG when you use LACP. You can see the example below.
