I was able to follow instructions to patch the AP file with magisk. I saved it to my SD card, removed the SD card and put it on my computer and flashed it with Odin. I now have the unlocked Bootloader warning and the not Factory firmware warning. I cannot get Magisk to give me root access. When I Boot to recovery with volume up, Bixby, and Power, if nothing is plugged into the USB C port it will not go into recovery at all. If I press all three of those keys almost any length of time with the computer plugged into the USB C Port, it will go into Factory recovery. It will never boot with magisk giving root access so I can further install Magisk and Root Checker always shows not rooted. I even tried plugging in the USB C while holding the buttons, and even unplugging it while holding in the buttons.
