I just hit the kill switch on my own app…

And honestly… every app should have this.

Right after pushing the new update, I wanted to test it like a normal user.

Very soon I spotted a bug. Because of a concurrency issue, some users who already had a username assigned could sometimes see the picker again… and sometimes not.

That’s the worst kind of bug.

It works.

Until it doesn’t.

Completely random. Pure “luck” depending on what runs first.

So I didn’t risk it. I flipped the app into maintenance mode. Everyone sees a simple screen, no interaction, until it’s fixed. Not fun… but way better than letting users run into broken logic.

I always knew I’d mess something up eventually 🤣

This time it was concurrency.

If you’re building an app — have a kill switch.

You’ll thank yourself later.

Fix is already in app review.
