I have an app on both iOS and android platforms where I am using WKWebView for login using a Google account. I get this error message Authorization Error 403: disallowed_useragent. As mentioned in other older posts, can I set custom user agent for web view as a workaround. Is it still a viable solution considering Google will not allow web view to use Google Sign In.

There is information here about what to do on Android and iOS instead of using embedded webviews: https://developers.googleblog.com/2021/06/upcoming-security-changes-to-googles-oauth-2.0-authorization-endpoint.html#instructions

On Android, you can use Android Custom Tabs and on iOS, you can use SFSafariViewController.
