I added did the request from the PlayStation Partners side and have yet to hear back from PlayFab. It's been a few days at this point. :)
Once our SDK team receives the email from the Sony developer portal, they usually contact the developer (using the information sent by Sony) within two business days. However, it's worth noting that unless you need access to the Party libs for PS4/5, the API calls are already active for your title - you just have to configured the Client ID and Client Secret for your title in the Add-ons tab for the PlayStation Network.
