I have Mavic Air 2.  I’m using the latest  firmware 01.01.0720 on iPhone 12 Pro.  Never has any issues until a few days ago.  After a few minutes of flight the aircraft keeps disconnecting from the RC and loses video and telemetry, even when it’s very close by.  A message comes up in red saying RC not connected to aircraft, however the aircraft can still be controlled and brought back if you still have VLOS.
Can you help me with this issue please.

Hi, there. Sorry for the inconvenience. Please try to restart and link the drone and RC Pro controller several times to see if it persists. If it's convenient, please try to connect the DJI Assistant 2 to refresh the firmware.
