Creating an Online Session and transitioning to another map does not work in a Launched Windows game. The transition event does fire but it just resets the players position on the Default map.
This was reported and tested in 4.23 Preview 4 (CL-7647024). This was reproduced in 4.22.3 (CL-7053642) and Main 4.24 (CL-7748116)
Results: Online Session creation fails
Expected: Online Session creation succeeds
