Here's what I found to resolve this as desired!
Then (you need to click 7 times on) About Phone
That enables Developer Mode
Open Developer Mode, scroll down to the end.
Click on Force allow apps on external.
See that it is enabled with the slide to the right side!
This allowed me to do the following.
Open Settings> Apps Click on GoPro.
Click Storage, click Change, NOW it presents the option to make the storage location the SD card, which means moving the App and files to the SD!
REALLY WORKED FINE FOR ME, SO PLEASE TRY IT!

I tried tis on my Galaxy S7. At first it appeared to work, but all that actually got moved was the Android/data/com.gopro.smarty folder. The main video storage location is still 0(internal storage)/DCIM/com.gopro.smarty.
