Hey Matt, i spend fucking 450 dolar for my app. I'm developing an app on Replit... But I still can't understand the database stuff. If I have a project, let's say I've published it and users are registering. But when I make updates to the project and publish it again, users who registered a month ago are completely deleted. I'm also having trouble with the AI that sends emails because I'm getting translation errors from Turkish. Please explain this to me: My goal is to add updates to my project without deleting users. Project Name: Milyonuss
