SaaS Founders: What’s the one technical bug/issue you can't solve right now?

Let's do a "debug" thread. ​If you're currently building an app or software and you're hitting a technical dead end, post the details below. Please include: ​The Tech Stack (e.g., React, Node, Python) ​The Problem (What’s happening vs. what should happen) ​What you’ve tried so far ​I'll do my best to provide a solution or at least a new direction to look in. Let's get those ships launched!
