For WCN7850, ath12k has limited concurrency support. That means it might work with some
specific configurations, like channels etc..

Please share all necessary information to debug further, such as wpa_supplicant/hostapd
config, kernel/wpa_supplicant/hostapd logs, firmware you are using etc.

And by 'not working' please clearly describe the issue you saw.
