Cinematic camera lock to players camera, camera locked bug and player join in progress

So, there is an issue with the cinematic devices and we all know that, but we need to know what triggers it also, cause cinematic sequence devices right now is just a mess, some times the camera from the cutscene just stops and get locked in place while the match is still running, only returning to the Player camera when it dies! Thats a main issue with a main feature of UEFN, and I wanted to know what triggers it, what can we do for it to never happen, I tried the visibility and stop and everthing, still some times the player just get stuck on the cinematic camera… This also happens more often when players join in progress, but it happans anyway
