It seems a bit sad when DJI apparently ignores Apple users by not releasing the P4P app at the same time it releases the Andriod app. I use both systems and don't get any joy at seeing friends not being able to download a working app. Enquiries to DJI elicit the response that, summed up, says "we don't know". I am starting to believe those who I used to think were just whingers.

Hi, we'll release the DJI GO 4 for IOS as soon as possible.
Please keep an eye on our DJI website. Thanks you for your understanding.

Hi Mindy Thanks for your response. But it really still  is DJI doesn't know. I understand this is not your personal fault, however, just disappointing. If it's Apple's problem please let us know although Apple is not always responsive  to suggestions
