Mini 3 pro not connecting with DJI rc

I’m trying to update fly safe data and it gets to 40% and says update failed. Tried this many times. It gives a message that rc must be connected to aircraft. Try to connect as per instructions, but without success. A few times it has connected and shown camera view, but when I go back to update fly safe again, which is required, it says not connected to aircraft. Try to connect again and will not connect. Can anyone help please? Just bought this and haven’t flown it yet due to the above.
