## What changed

**1. Added: Update** (identified) · 2026-11-10 18:19 UTC

```diff
+ We have submitted reclassification requests to the affected vendors, and warnings are clearing for some users of Norton, AVG and Avast. We are now working with the remaining security vendors and threat list providers that still flag retool.app. Because published React-based apps and the app builder preview built with the React-based app builder are served from retool.app, affected users may see those apps or the preview fail to load, often with a connection timeout and no warning page. Some VPNs, routers and company web filters can also block the domain. Apps built with the classic editor and the Retool editor itself are not affected. Retool services are operating normally. If your IT team manages these products, they may be able to add an exception for *.retool.app. We will post another update as vendors confirm.
```
