Not sure if this help someone:

In my case “update_sub_field()” fails to update POST_META table:
It creates an additional record for the post without repeater name:

_0_subfield
_1_subfield
_2_subfield

and does’nt update the good records:

repeaterName_0_subfield
repeaterName_1_subfield
repeaterName_2_subfield

And from them it updates the wrong ones, “update_sub_field()” seems like the function fails to “add” repeater name to the meta_key, anyway I found a workaround:

Use the core function “update_post_meta()” :

update_post_meta( $post_id, “repeaterName_0_subfield”, “new value” );
update_post_meta( $post_id, “repeaterName_1_subfield”, “new value” );
update_post_meta( $post_id, “repeaterName_2_subfield”, “new value” );

This function update values in custom fields in Post_Meta table.
PD: If you need to know how many “rows” has your repeater you can use this:

$number_rows = get_post_meta( $post_id, “repeaterName” );

This works for me perfectly, I spend a lot of time struggling with update_sub_fiel(), hope there will be an update it soon.
