How to configure several Mikrotiks connected via a switch to two subnets and two WANs?

Question

Mikrotik

The network diagram is as in the picture: It is

required that 192.168.0.0/24 go through WAN1, and 192.168.1.0/24 through WAN2.
At the same time, the switch with Mikrotiks No. 3 and No. 4 is connected by one twisted pair.
I put on Mikrotik No. 1 - 192.168.0.1, on Mikrotik No. 2 - 192.168.1.1. On both lifted the Internet.
On Mikrotiks No. 3 and No. 4, I combined ports 2-5 into a bridge and assigned separate DHC servers to the bridge and WLAN with the corresponding subnet.
And then it stalled, because. so that I don’t make packages from Mikrotik clients No. 3 and No. 4, they don’t go further than Mikrotiks themselves. They don't even go through the locks.
I've looked all over the internet and still don't know what to do. Tell me please.

It is logical that they will not go, it is necessary to do routing. Make all packets go through at least one WAN. Then, through the pbr or vrf mechanisms, scatter them to different gateways. And make more logical addressing with normal subnets on each piece of hardware, and not just with a range of addresses
