API subscription Lists Object does not work

[Yo-Fly]

Hi,
I set up a custom Subscription Form being sent to “/wp-json/newsletter/v2/subscriptions” a while ago and eventually got everyhting to work.
RIght now I am experiencing one issue with my listsobject as it is being ignored when creating the new subscriber.
I am using this syntax (as the example in the Swagger UI):

{
    "email": "foo@bar.de",
  "lists": [
{
      "id": 4,
      "value": 1
    },
{
      "id": 5,
      "value": 1
    }
],
  "last_name": "Foo"
}

The lists are public and yet not being set.

However, if I use the alternative with just an array of to be set lists, it seems to work:

{
    "email": "foo@bar.de",
  "lists": [4,5],
  "last_name": "Fleischhut"
}

I would prefer the first way, though, as some of the lists are set dynamically, so sometimes I will put a 0 and sometimes a 1.
Am I doing anything wrong or missing anything? Thanks in advance!

Hi, which version of the Newsletter API are you using? Could you kindly check the addon version? There was a bug on the previous version.
The second format (array) can be used with a negative number to unset a list (yes, it is not correctly documented).
