iPhone 8 OTG

Currently have a DJI Drone (Spark) and the FPV goggles, the DJI site, says that I need the "Apple Lightening OTG" cable (female USB) to connect the Goggles to the RC (which only has a micro USB connection) and the FPV goggles have the same, the FPV goggles come supplied with a USB - Micro USB (used for charging the FPV Goggles).

Does the Iphone 8 still support OTG cables, as I can not find the cable on the Apple store, and whilst DJI do supply the cable at £5, they charge £10 postage which is expensive to fork out if I don't know if it will work or not.

I also read that if you connect the FPV goggles to the RC, the iPad/Iphone display you use with the RC will not display the video feed due to the Ligtening connection disabling the Wi-fi link from iPhone/Ipad from the DJI App.

Any advice greatly appreciated.
