Have been flying since 2017 phantom 3 standard p4p plus and decided to try the mavic pro as the price for it now was cut in half. had it 4 months and im no longer seeing the flight minutes on my mobile iPhone xr . Their is a white blot over the time data. never saw that before on any dji drone. Ive uninstalled dji go 4 app reinstalled calibrared everything disconnected remote from mavic relinked and even refreshed firmware. switched phones and nothing brings back the time remaining for flight to reach rth. Hope some long term pilots have a idea as to what is the reason for this? don't really want to have to engage the care refresh if their is a simple solution. No other problems exist due this yet it could be a sign of a future and larger problem or loss of the mavic itself?Screenshot attached?
