I am also unable to get new subscribers created via POST /subscribers to be assigned to a list. They are created without being assigned to any list at all regardless what id value is given.
Furthermore, the V2 api documentation does not indicate what is the purpose of the request data list "value" and "list_N" properties.
`
"lists": [
{
"id": 2,
"value":1 <-- ?
}
],
"list_N": 0, <-- ?
`
