Hi @digitalquery
Thanks for the code. I did a bit of digging into the wp_update_user and it seems that ACF is not hooking into the actions which this function uses.
I’ll add this to the to-do and make sure I update the actions to use these.
For now, I’m not sure what the solution is. Perhaps you could modify the core code in /core/controllers/everything_fields?
Sorry that I don’t have a great answer for you at the moment.
Thanks
E
