Google Home devices needing to be power-cycled with RB4011

RouterOS Wireless Networking
1

I’m having the same issue as in an old thread here on my RB4011iGS+5HacQ2HnD running RouterOS 7.13.4 (stable).

After a reboot, the router logs show nothing until the devices are power cycled, at which point they immediately connect with no issue:

44:07:0B:XX:XX:XX@wlan1: connected, signal strength -38
DHCP-LAN assigned 192.168.1.11 for 44:07:0B:XX:XX:XX Google-Home-Mini
30:FD:38:XX:XX:XX@wlan1: connected, signal strength -80
DHCP-LAN assigned 192.168.1.12 for 30:FD:38:XX:XX:XX Google-Home-Mini
38:8B:59:XX:XX:XX@wlan1: connected, signal strength -48
DHCP-LAN assigned 192.168.1.14 for 38:8B:59:XX:XX:XX Google-Home-Mini

WiFi configuration from export (can provide more excerpts, if need be):

set [ find default-name=wlan1 ] band=5ghz-n/ac channel-width=20/40/80mhz-XXXX \
    country=canada2 disabled=no distance=indoors frequency=auto installation=\
    indoor mode=ap-bridge ssid="[5GHz WiFi]" station-roaming=enabled \
    tx-power-mode=all-rates-fixed wireless-protocol=802.11 wmm-support=enabled \
    wps-mode=disabled
    
    /interface wireless security-profiles
    set [ find default=yes ] authentication-types=wpa2-psk disable-pmkid=yes mode=\
    dynamic-keys supplicant-identity=MikroTik

Thanks in advance for the insight!
