Iphone 15 Pro Max - Can't see Wifi6E network in Argentina

Hi,

We have been testing WiFi6E (6GHz band) in different locations and for some reason, when we are in Argentina specific, without any change in the software we are no more capable of finding the 6GHz network.

Is there any specific blacklist that could explain this situation?

It is funny that Ipad13 (wifi6e capable) and Iphone16 (wifi7 capable) are well able to see it in the same location.

Also, if we move back Iphone15 to Brazil for instance, all is fine again, we are able to see the 6GHz.

All this tested against the same AP.

Does anyone had such issue?
