Minecraft sneaking 1.15?

Hi, since the new snapchot is out I can't sneak anymore

If I just briefly press the button (do not hold down) I sneak and if I want to stop sneaking I have to press the button again

Can tell me if I can turn that off

Look in the settings. There should be something like "hold for sneaking" or something.

It's called "Snapshot"

I looked under options> controls and unfortunately I didn't find anything
