I’m currently learning MERN. I cloned a repo, and try its MERN stack functionality, it all worked, I was able to register and login, but when I look at my collection, theres no any data, weirdly, I deleted my cloned repo, and redo the cloning again, and I can still login with the information I register on previous file. Im certain that I setup the correct Mongo URI. Any explanation and solution with this?
