Site to Site VPN (13 Sites & 2 remote Laptops)

Sorry to bump this thread, but, is split-tunneling in Windows 10 and RouterOS v6.46 stable working for anyone? (IKEv2)
I’ve caught this bug report: http://forum.mikrotik.com/t/bugreport-split-include-buggy-for-at-least-ikev2-6-40-2-current-and-6-41rc18/111635/1
Which was fixed: *) ike2 - send split networks over DHCP (option 249) to Windows initiators if DHCP Inform is received;
But, something isn’t working.
Windows connects, gets the assigned VPN IP on the interface but that’s it.
I sniffed packets on the router’s wan interface and I can see the DHCP Inform coming from the Windows 10’s VPN IP, so somehow that doesn’t reach ipsec?
I even tried with all drop rules from the firewall disabled, no luck.
If I check “use default gateway on remote network” on the windows 10 TCP/IPv4 settings for that VPN connection all the traffic gets routed through the VPN, works, but not ideal.
Windows version: 1809 build 17763.864.
LE: I’ve tested with v6.44.6 Long Term, same thing.
