I'll check it later, long download for me.
Teleporting and sync-shot both working fine for me. F3 in the map to capture, exit the map before using F4. Activate sync-shot when in the game. Are you sure your not confusing the time it takes for your team to set-up the shot, it takes a fews seconds for them to get into position, once use I could use it right away again, just need to wait for AI teammate to set up the shot.
