Facebook Graph API since/until Not Working for Facebook Conversations – Facebook api

For other nodes, such as Posts, I can easily retrieve the posts newer than the specified date via since

me/posts?fields=id,link,created_time&since=2017-05-23

However, for Conversations, since doesn’t work as expected, as you can see below (both of the results were created/updated older than 2017-05-23)

According to the Facebook documentation, I believe all nodes should support time-based pagination, but only conversations and messages don’t work as supposed.

I don’t want to fetch the private messages and manually check the updated time to filter out the old messages because all of other nodes use since to filter the results and also, manually filtering the results is not a long-term solution.

Any alternatives for fetching Facebook messages by specified date?
