Google has published a Chrome 86 notification referring to Trusted Web Activity which will delegate some web app errors to native app crashes.

Starting in Chrome 86, Chrome will integrate critical web application crashes into native app crash events and Android Vitals. As this change will cause user facing crashes if these events are unhandled, developers using or planning to use a Trusted Web Activity should review this post carefully.

Critical web application crashes that will be delegated in Chrome 86 are:

an HTTP 404 or 5xx error in the application

failure to return HTTP 200 for an offline network resource request

failure to verify digital asset links at application launch

The article provides detailed information on the exception conditions, the impact on the app behaviour, and avoiding these exceptions.
