Sanity React App SDK v2.10.0: Automatic chunk-load recovery and login error fixes

This release improves reliability with automatic recovery from chunk-load errors, along with two fixes to login error handling in standalone apps.

Automatic reload on chunk-load errors

The app now reloads automatically when a JavaScript chunk fails to load. This commonly happens after a new deploy invalidates cached assets, and previously left users on a broken screen until they refreshed manually. No code changes are required to opt in.

Notable bugfixes and improvements

LoginError now stays synchronous in standalone apps, so error handling runs in the same tick as the failure.

The LoginError auto-logout flow guards against re-entry, preventing duplicate logout attempts when an error fires mid-logout.
