second this, would love this feature. I can’t draw freely enough, like other whiteboards, for making wireframes

Agree, just came across this post hoping to find a way to disable it

Yes, we need the same ability as a figma file to disable snapping. Its far to rigid for a “fast” drawing tool. I run in to to many times where I am not able adjust the size of an object to the exact size I want. 

checking up on this a month later, still would love this feature. It’s too hard to freely sketch UI ideas with snapping always on. 

or another solution, though less ideal to turning snapping off, would be to allow a custom grid size so it can be set very small for the use case of people wanting to sketch with boxes

I requested this very feature like five years ago, so don’t hold your breath :-(

Actually, this made me do some more googling, and it turns out they DID add this feature! Press and hold the S key while moving an object, and you break out of snapping!

My use case is that I want a connector to begin at the end of a line of text 
(e.g. “Press Submit -->”).
If the text you want to connect to ends at the very edge of the text box the connector will constantly snap to the grid. Extend the width of the text box with a few spaces, hold down the Command key (Mac) and you will be able to position the connector precisely. 

Update: I found this works with shapes as well. Create a shape, make sure the connector is in front of the shape, make the shape transparent and with no line. Press Command and move the endpoint over the shape and position it precisely. What a hack. But it works.
