You made the error of having a bridge subnet, get rid of it and assign another VLAN. Due to this you failed to clearly identify this other subnet which seems to be at least intended for ports 4,5,6 and sfp-sfpplus1 ???
You also seem to be adding WAN ports to the Bridge which is not usually required in most scenarios.
You also do not seem to know how to use vlans properly when it comes to /interface bridge ports and /interface bridge vlans.
You have duplicate pools, both pokucni and pool6 are identical???
If vlan50 is home then WTF is 192.168.88 subnet?? Should I assume this is for the admin only???
Why if there are six vlans now ( seven when you remove bridge from doing anything directly with a subnet and assign a vlan to .88) do you have 8 pools??
(four for apartments 1-4, one home, one iot,)
Vlans required because the ISP provides connectivity via a VLAN do NOT require pools, servers, gateways etc…
Bridge ports should EITHER be in one of three formats
access port (going to dumb device)
add bridge=bridge ingress-filtering=yes frame-types=admit-only-priority-and-untagged interface=X pvid=YY
trunk port (going to smart device)
add bridge=bridge ingress-filtering=yes frame-types=admit-only-vlan-tagged interface=A
Hybrid port (rare going to device such ad voip phone or unifi ap)
add bridge=bridge interface=B pvid=ZZ
Change detect internet TO: none
Dont think you quite understand firewall rules yet. What is the purpose of the first rule given the third rule.
add action=accept chain=input in-interface=vlan50-home-lan
add action=drop chain=input disabled=yes in-interface-list=guest-vlan
add action=drop chain=input comment=“defconf: drop all not coming from LAN”
in-interface-list=!LAN
IF not using IPV6 suggest disabling and removing any associated lists and filter rules
Suggest reading the following link first to help understand where I am coming from.

Feel free to ask questions but it would be premature for me to comment on the file as its to full of basic errors at the moment, so more understanding is required.
