AR300M cannot find APs at all with iPhone

I have a AR300M that works perfectly as a VPN router when I’m travelling using the free wifi internet at different hotels and friends’ home wifi. However, the problem is that with my

IPhone 5S, iOS 12.4.1
Using Firefox, Safari or Chrome

When I Scan for access points, it does not return any results.

My Samsung S10 running Android has no problem.

I have allowed pop ups and ensured JavaScript is enabled for Safari

I am sure this is a BUG, the landscape screen can be shown, the next version of the firmware will be fixed

Thanks a lot, looking forward to it
