When creating an ICoordinateTransformation between 2 CoordinateReferenceSystems in some cases the returned transformation may attempt to use a transformation grid that is not available #106
This issue is due to the sort order of returned transformations returned by proj9.0 including transformations that use a transformation grid when the grid file is not available.
solution is to change proj_operation_factory_context_set_grid_availability_use to use PROJ_GRID_AVAILABILITY_USED_FOR_SORTING.
Previously it was using PROJ_GRID_AVAILABILITY_IGNORED
