Wireless roaming to HAP ax3 - no network access after this

Good day!
Encountered very strange problem I am unable to solve.
Two access points - Apple AirPort Extreme & Mikrotik HAP ax3.
Configuration of ax3 is the very basic access point. Initial config removed, setup from scratch. Wifi 2 and 5 on same SSID; all eth ports and WiFi bridged together. DHCP client on bridge, all heavy lifting done on main router. Thats it, no firewall no nothing. All works fine, clients get DHCP leases from main router, can access internet.
Configuration of AAPE - access point, same SSIDs as on Mikrotik,WiFi 2 and 5. Not much to configure there. All is working here just fine as well.

Now to strange part. Tested on iOS device and Windows laptop.
When I move from Mikrotik coverage zone to Apple, devices immediately switch APs and all is working fine.
When I move from Apple to Mikrotik, it begins. Devices connect, I can see them associated in HAPs Winbox. But there is no network connectivity. I cant ping anything - even main router. At the same time, HAP itself continues to serve other clients just fine and can ping anything I throw at it. For some reason only the cleint that roamed from another AP looses network access despite being associated with HAP and keeping healthy connection. This continues for like 5-10 mins and after that network access comes back and all is working fine until I do AP swap from HAP to Apple and back.

I tried all I could think of: harmonized APs as much as I could (WPA2 only for security, only basic HAP settings for WiFi); used different SSIDs for Apple and HAP; added static ARP entry for main router for AP and some other minor stuff ChatGPT suggested )
Nothing helped, the problem is persistent and reproduces every time I test for it.

I hope to find some help and peace of mind here )
Thank you in advance.

+1, same problem; other environment
CAPSMAN v7.18 with 2 cap ax. So they have both the exact same configuration, being managed by same capsman.
Roaming looks ok, client changes AP, but there is no network connectivity for about 10 minutes. Devices announce “Connected, no internet access”.
If you just wait, at some point the connection comes back online. So there might be some kind of timing out somewhere.

Tried different bands (ax, ac, etc), different FT (on/off).

CAPSMAN config:

# 2025-06-06 13:17:44 by RouterOS 7.18.2
# model = CCR2004-1G-12S+2XS

/interface wifi security
add authentication-types=wpa2-psk disabled=no name=sec-informatique passphrase=WhoCares

/interface wifi datapath
add disabled=no name=dp-1087 vlan-id=1087

/interface wifi configuration
add country=France datapath=dp-1087 disabled=no name=cfg-informatique \
    security=sec-informatique security.ft=no .ft-over-ds=no ssid=Informatique

AP config:

# 2025-06-06 13:31:41 by RouterOS 7.18.2
# model = cAPGi-5HaxD2HaxD

/interface bridge
add name=bridge_lan protocol-mode=none

/interface bridge port
add bridge=bridge_lan interface=ether1

/interface wifi datapath
add bridge=bridge_lan disabled=no name=datapath_local

/interface wifi cap
set caps-man-addresses=10.85.0.254 enabled=yes slaves-datapath=datapath_local slaves-static=no

Ha, and I thought it was because of hardware mix. If the problem manifests on pure Mikrotik setup must be some nasty bug.
