We are aware that some creators are unable to start a session in UEFN.

Creators may also be receiving cooking errors when trying to push changes to UEFN islands, and players trying to join UEFN islands may receive matchmaking errors.

We are looking into these issues and will provide an update when we have more information or a fix.

We've been monitoring and this issue appears to be resolved. We'll keep an eye on things and let you know if there are any updates.

Thank you for your patience while we worked things out!
