The systemd service hostapd is enabled and when the system is started
the service reports that it is up but none of my Wifi devices can find
the network.

Nov 28 23:52:31 raspberrypi systemd[1]: Starting Access point and
authentication server for Wi-Fi and Ethernet...
Nov 28 23:52:31 raspberrypi hostapd[492]: Configuration file:
/etc/hostapd/hostapd.conf

UNINITIALIZED->COUNTRY_UPDATE
Nov 28 23:52:31 raspberrypi systemd[1]: Started Access point and
authentication server for Wi-Fi and Ethernet.
So I have to shutdown the service with a # systemctl stop hostapd and
then start the hostapd service manually.
# hostapd -dd /etc/hostapd/hostapd.conf.
When the hostapd service is started with the method above my wifi
devices are able to find the wifi access point.
I don't find anything in the logs which point to the issue and both
methods use the conf file /etc/hostapd/hostapd.conf to start the
service via systemd and manully.
Here is a copy of the hostapd.conf file:
# cat /etc/hostapd/hostapd.conf
