F11s 4K Pro WiFi Problem

Received my new SJRC F11s 4K Pro two days ago. The SJRC F11 4K Pro is a rather good drone. Of the $200-$250 drones, this F11 4K Pro is stable, has stabilized Gimbal, 4K video (although not very very 4K compared with Mini 2, Mavic Air, etc.), etc., and well-built. I like this drone very much. So, when the new F11s version with a flight distance of 3km was released I ordered one. Unfortunately, this drone did not connect to my phones: iPhone X and iPhone 12 Pro MAX. I tried to connect the drone and my phone for two days without any success. I gathered that this drone has a malfunctioned WiFi component. I am very disappointed as in recent days Chiinese drone makers may have a quality control problems. This video was taken as an evidence showing to the seller that this drone is defective. Hope I could get a working version so that I could share its images and videos with you before the winter arrives.
