Hello John,
the problem only occurs with existing rows…
Explained in other words:
When I use get_sub_field after I used update_sub_field,
I get the old value from before the script,
not the new just updated value.
When I use add_row,
everything done before with update_sub_field is gone.
It seems to me that a cache is used.
This only happens if the steps are in the same php script execution.
If I do it later / on another page, it works fine.
