I have a DJI Spark; no historic issues but I have a new iphone.  The RC will connect to the Spark without issue - but the phone will not connect to the RC.  When I input the password in wifi connection 12341234 it says not recognised?  What do I do please?  Had the problem repeatedly today.

Hello, there. Sorry for your inconvenience. Would you please check the Wi-Fi password first? You can check the Wi-Fi SSID and Password inside the battery compartment or under Wi-Fi Settings in DJI Assistant 2.
The original Wi-Fi SSID and Password can also be found in the foam package box. If the issue persists, please reset and Wi-Fi password and try again.
