Didn't see a tab to report issues at https://github.com/PlayFab/PostmanCollection so figured I'd share here!
The multiplayer/ListMatchmakingQueues entry gives a 404 response until changing multiplayer/ portion of the URL to match/
The v2 Postman collection is also no longer importing headers properly, resulting in needing to add e.g. Content-Type: application/json manually to each entry.

Currently playfabV2.json has known issues. You can refer to Importing and exporting data | Postman Learning Center to manually convert playfab.json to v2 version.
This issue has been fixed. Please try again with playfabV2.json. If there is any issue, please don't hesitate to let us know!
