Well, I went back to version "46" this weekend and was very careful and it worked fine...sort of...long story short...it worked, flew well one time and then I couldn't connect again. I finally saw where you cannot format your SD Card in Windows 10 ExFAT system. I'm a believer. I reformatted my Samsung 128gb sd card with a 3rd party software to reformat to the FAT32 system and it all works great now.
Even after I updated with Camera update firmware files using a FAT32 card...I put my just plain old 128gb (EXFAT) card back in just for recording videos and it stopped connecting again so that when I finally had to use a third party software to format it in FAT32 formatting. Now it connects and records video every time … so far
