Cannot get STA-AP to work with piZero 2

[mcdullmedia]

I have tried everything mentioned in the tutorial. No reboot before enabling STA+AP mode.
The best I could get is zero2connected to my other AP as client, and AP mode visible.
When my other device connecting it, no ip is assigned. Even I manually entered IP, no internet on the client.
DHCP server is bind to uap0 but didnt work.

And rebooting the zero2 will randomly connect using wlan0 or uap0 (I have meshcentral installed so it tells which interface connecting to the host network)

Tried to search for similar issues, solution not working. Thank you.

Per the AP-STA doc page:

This mode is completely unsupported and should be used for educational purposes only. If you need a reliable solution with an access point (AP) and wireless client (STA) on the same device, buy a second Wi-Fi adapter and follow this FAQ instead.

hey @mcdullmedia go to Hostpot and then Logging, what error(s) do you see.
On my Pi Zero2 W I get the below errors when I try to enable STA-AP which looks to me like either we need to specify a different driver to use for the uap0 interface, or the the Pi Zero2 W can't actually support this mode.

uap0: interface state UNINITIALIZED->COUNTRY_UPDATE
uap0: INTERFACE-DISABLED 
uap0: INTERFACE-ENABLED

Ok it looks like i missed this note ( #752 (comment) ) about needing to "stop hostapd, disable AP-STA, make your config changes on wlan0, re-enable AP-STA and start hostapd.". Ive got STA-AP working on my Pi Zero2 W now
