In December 2024, I wanted to start my step accuracy testing but quickly discovered that my [Circular Slim](https://www.lordofthesmartrings.com/circular-slim-v2024-review/) was unusable. I encountered the error **"ES02: Upload Error."**

"Ok," I said to myself, "maybe it’s just a connection issue. It’ll work later." Nope.

So, I tried the usual troubleshooting steps: force-closing the app, disassociating the ring, and reconnecting it. Still nothing.

Fortunately, I had another Circular Slim for my testing! But guess what? The same issue. At that point, I braced myself and contacted customer service.

**Long story short** (after a lengthy conversation with support)—they said it was not possible to fix. Their solution? A discount for the Circular 2.

Hm.

## A Strange "Fix"

In February 2025, I finally initiated my step accuracy testing. I remembered that I still had a [Circular Pro](https://www.lordofthesmartrings.com/circular-ring-full-review/). It was old, but it looked functional. So, I associated it with my Circular app.

And guess what happened? **Error ES02: Upload Error.**

Three Circular rings affected by the exact same issue? Or was it something with my account?!

🆕 Out of curiosity, I created a new account on my Android phone (I originally used an iPhone). And you know what? **All of them started working.**

The downside of this fix? I lost all my historical data.

I have no idea how this is possible. If someone from Circular is reading this, please explain.
