TUF-BE3600_V2 Dual WAN tab missing in web GUI

[pseu_asus]

Not sure why I can't find the dual wan tab in Advanced Settings-->WAN, some people said it may move to Network-->Smart Home Master, but I couldn't find it there either.
Firmware version: ASUStek stock image 3.0.0.6.102_39099
Reboot the device did not make it show up.
Any idea of it. Just don't want to reset it to factory settings and re-do all the config again.

I went to ASUS' webpages and checked this TUF-BE3600 and TUF-AX3000 V2, then I went to check the RT-AC68U specs (because I am familiar with that model that it has Dual WAN). Only the RT-AC68U said "Dual WAN" in the specs...

Entry-level devices may not have all the features available.

I have some clues now. I had configed "dual wan" with the factory firmware days ago. However, recently ASUS released new firmware for this model and the DUAL WAN tab might be removed in the latest firmware.
However, in nvram settings, the configs are still there. Seems the previous configed dual wan still works.

# nvram show 2>/dev/null | grep wans
wans_cap=wan usb lan
wans_dualwan=wan lan
wans_extwan=0
wans_lanport=4
wans_lb_ratio=1:1
wans_mode=lb
wans_routing_enable=0
wans_standby=0
wans_usb_bk=1
wans_usb_bk_act=0
wans_routing_rulelist=

# nvram show 2>/dev/null | egrep "wan[01]_state_t|wan[01]_proto_t|wan[01]_enable|wan[01]_ifname|wan[01]_uptime"
wan0_enable=1
wan0_ifname=eth0
wan0_proto_t=pppoe
wan0_state_t=2
wan0_uptime=378670
wan1_enable=1
wan1_ifname=vlan2
wan1_proto_t=pppoe
wan1_state_t=2
wan1_uptime=378676

So you mean the hardware is dual WAN capable, ASUS accidentally enabled it in the older firmware, and now intentionally removed the capability? (That's a real bummer if so).
