I'll try the one you pointed me at below and post back.

all three platforms I was able to successfully download dives using
Subsurface 4.7.8.  I take that to mean that I have the correct permissions
on the platforms so it is just down to the difference between the -NG and
4.7.8 branches.  I can generate Subsurface and libdivecomputer logs if that
would help.
