To work around the problem, we dropped the security from WPA3 Enterprise to WPA2 Enterprise, in order to disable PMF. Just not entirely sure whether this is the best approach to accommodate Huawei mobiles...
1. As the issue is occurring only on Huawei Smartphones, to determine if the cause is FAP-231F radio or authentication related. Please test Huawei Smartphone WiFi connection on a Test Open authentication SSID on FAP-231F
2. If downgrading from WPA3 to WPA2 has resolved Huawei Smartphone WiFi connection issue then please check Huawei Smartphone specs sheet and verify if it supports WPA3 security mode
Please log a new FortiAP Ticket with Fortinet Support if the issue persists on the Test Open SSID on FAP-231F
