What Is the Perplexity AI Broken After Update Issue?
Perplexity AI is regularly updated to improve performance, accuracy, and features. But sometimes, right after an update—whether on the web, iOS, or Android—you might notice things suddenly stop working. Common symptoms include freezing, unresponsive prompts, blank answer boxes, login issues, or missing interface elements. In other words, the tool feels broken immediately after what should have been an upgrade.
This “Perplexity AI broken after update” issue is frustrating, but it’s usually tied to temporary compatibility conflicts, cached data problems, or outdated device or browser settings. Fortunately, it can often be resolved in a few simple steps—without needing to undo the update or wait for a patch.
Why this matters:

Instead of boosting performance, the update causes unexpected downtime. - 🧠 Creates Confusion Around What’s Actually Wrong

Even with a fresh install, the system might load old data that conflicts with the new version. - 📱 Affects Both App and Web Versions
Whether you’re on desktop, iOS, or Android, similar issues can arise after major updates.
Let’s explore the causes—and how to fix them.
