Bug in Canvas - Keeps trying to overwrite

Is anyone else having issues with Canvas.
Whenever i try to get it to update and improve a single sec of a document
it overwrites it instead and deletes the original

I could talk about Canvas’ problems all day. Once a coding project gets big enough management gets hairy and using Canvas should help. But it doesn’t feel like anyone is listening.

For a while there Canvases started to get absolutely amazing. Now it feels worse than when they first came out. Consistently overwriting, randomly writing on a canvas when not asked, not actually being able to contextualize what is on the canvas, and now not even being able to edit inline without nuking the whole damn thing is a REAL buzzkill.
