FailOver Mikrotik

Good evening everyone
I have a problem
My failover doesn't work, or rather it works partially
Here is my configuration

WAN 1 - 192.168.1.X/24
WAN 2 - 192.168.220.X/24
LAN - 192.168.88.X

On WAN 1 I have an ADSL modem
On Wan 2 I have a 4g modem

These are the set routes

C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme,
B - blackhole, U - unreachable, P - prohibit

DST-ADDRESS PREF-SRC GATEWAY DISTANCE

0 AS ;;; Primary WAN1
0.0.0.0/0 8.8.8.8 1
1 SD 0.0.0.0/0 192.168.1.1 1
2S ;;; Secondary WAN2
0.0.0.0/0 192.168.220.1 2
3 AS ;;; Validate Primary
8.8.8.8/32 192.168.1.1 1
4 ADCs 192.168.1.0/24 192.168.1.9 ether1 0
5 ADC 192.168.88.0/24 192.168.88.1 bridge 0
6 ADCs 192.168.220.0/24 192.168.220.10 ether2 0

The problem is as follows

If I unplug the WAN 1 cable on the mikrotik manually then it automatically switches to WAN 2
If instead I disconnect the ADSL cable on the modem of wan 1 the switch does not work

Where am I wrong?



Looking forward to your suggestions

Is what I would attempt to config…

/ip route
add distance=5 check-gateway=ping dst-address=0.0.0.0/0 gateway=8.8.8.8 routing-table=main scope=10 target-scope=12
add dst-address=8.8.8.8 gateway=192.168.1.1 routing-table=main scope=10 target-scope=11
add distance-10 dst-address=0.0.0.0/0 gateway=192.168.220.1 routing-table=main

As for your issue, concur it seems to make no sense. Either way the router is not getting a signal on the WAN port.
