When using GET lists/list instead of v1 GET lists, there are important differences, although the documentation states that:
“This method used to be GET lists in version 1.0 of the API and has been renamed for consistency with other call”.
Issue #1 - GET lists/list returns only the first 100 lists. This is not documented and there’s no cursor support.
Issue #2 - GET lists/list returns different content than the v1 call. GET lists returns just lists owned by the user, and GET lists/list returns all subscribed lists.
