Thanks for sharing !
by the way why didnt you use the #1 import plugin on the market : WP all import :
https://www.ads-software.com/plugins/wp-all-import/
it has 100K users (compared to 20k users for the plugin you used)
is there a specific reason why you chose this one ?

i think both are working but WP all import is the gold standard ??
As CSV or XML feeds we need to import are very different and can come in various formats, a plugin like WP all import (or yours) is the right solution, as it would be quite impossible for Radius to develop an equivalent feature with so many features
the best solution would be to increase (if needed) the compatibily between radius classified plugin & WP all import
