I have noticed recently while using the Dongle V2 with my Mini 4 Pro
I that Mini is losing GPS 2 or 3 times per flight and dropping to atti mode
with the relevent warning on screen ,  I dont have the same issue if the dongle
is not used or the Mini still has RC control , only when I lose normal RC and the mini reverts to full 4G
for control .   it only lasts for up to maybe 30 seconds or less.

hope I explained properly

Hi there,
thank you for reaching out.

Can you please confirm what specific error/waning message you received? Also, please make sure that the drone is running the latest firmware, calibrate the compass, and change location for further testing.

Kindly feel free to let me know about the latest progress. Thank you.
