How to support old Android WebView?

I am trying to run an ionic vue 6 app on an Android 8 device. Its Chrome WebView version is 57. But it does not work properly.

How to support such an old Chrome version? Is there a polyfill to do this?

Try editing either the .browserslistrc file or the “browserslist” entry in package.json (one of them should be set already) to support older Chrome versions.

Note that Browserlist apparently doesn’t support specifying older versions of Android Webview, so try adding the same settings for desktop Chrome as well.
