## Updates from Expo
### 2026-04-28 22:44 UTC: resolved
Between 3:44 PM and 4:08 PM PDT, existing sessions on expo.dev were treated as invalid, and users were unable to sign back in. During this window, login attempts from the website failed. The issue has been resolved and users can now sign in normally. We're investigating the root cause.

From the builder: does your app depend on Expo? [Sazabi](https://www.sazabi.com/?utm_source=down-guide&utm_medium=markdown&utm_content=expo) detects problems in your own logs without hand-written monitors, and you can ask it in plain language which errors mention Expo.
