1. topology : internet - modem1/modem2 - ER605 load balancer - AX73 - clients
AX73 set as wireless router mode. I also choose "modem - ax73 - client topology" when I do first setup guide.
2. I tried that beta FW. I can open whitelist, but I cannot add device using device list menu. I cannot select/click the device that I want to add. It only work using manual add mac/device, and sometimes also have "operation failed" when add mac manually. Quick question, how many max device I can manage in AX73 parental mode?
3. Too bad, in public emulator using previous FW, AX73 still have QoS and Parental menu.
You guys should bring back the menu, It achievable in previous FW. Don't force people to install tether app as requirement for QoS/parental please?
4. iPhone/iPad tether app ver 4.9.14(Build 726) and android 14 tether app ver 4.9.26. Both don't show live network usage.
I tried to factory reset ax73. Still don't show live network usage.
5. I found AX73 another bug, when I access AX73 using WAN ip address, it often to redirect to "http://tplinkwifi.net/".
Meanwhile I already finished the setup and don't need that unnecessary repeated redirect to "http://tplinkwifi.net/".

Best regards.

  @Marvin_S No whitelist from that beta firmware in that thread is not working properly.
Whitelist don't have check mark to add from device list.
So I need to add all the device manually one by one.

Meanwhile in blacklist there are check mark to choose from device list.

Best Regards.
