King of Thieves – How to Jump Instantly Upon Starting the Dungeon

Some player's dungeons kill me instantly unless I jump immediately upon entering. This is practically impossible for me; no matter how quickly I double-tap, I can only rarely perform this jump. Actually, it doesn't even work at all anymore! Is there any trick to pulling this off? I have to skip a lot of dungeons because they have traps right near the door, or the door in midair… I reported this issue to the devs, but they say it is possible to pull off with skill!
