Long Range with iPhone and nRF52840 dev kit

[JesseJ]

According to this thread, iPhone 11 Pro supports Long Range (Coded PHY) : https://devzone.nordicsemi.com/f/nordic-q-a/33060/is-there-any-smartphone-with-supporting-of-bluetooth-5-long-range-feature/221305#221305

I'm attempting to test Long Range advertisements with a nRF52840 dev kit and an iPhone 11 Pro.  I made the following modification to the ble_app_rscs example in the SDK v16:

init.config.ble_adv_primary_phy      = BLE_GAP_PHY_CODED;
init.config.ble_adv_secondary_phy    = BLE_GAP_PHY_CODED;

Now when I run the project on the dev kit, I no longer see the device in the nRF Connect app on my iPhone.

Am I doing something wrong?  Is there some other setting that needs to be changed in the example project?

Does the iPhone 11 Pro actually support Long range?  If not, does Nordic have a list of known mobile devices that do support Long range?

Does iphone 11 support long range advertisements? 
I ask because there's high chance it's not as scanning for advertisements on Coded PHY is very expensive on a multiprotocol modem. It has to service Wifi and BT classic as well, and Coded PHY takes 8x more time on-air than 1mbps.
