问题
my team uses firebase auth and we recently run into major problems. We started advertising our website on facebook. Unfortunately, facebook app opens all the links in the in-app webview. Google blocked support for signing in with provider through embedded browser, so none of the users that opens our webapp through facebook/messenger/instagram apps can sign in. Google/Facebook sign-in returns 403: disallowed_usegagent and it is impossible to sign up. Is there any workaround? Has anyone experienced a similar issue?

Not sure about Google, but for Facebook I would recommend:
- do not use SignWithPopup in firebase
- set
Embedded Browser OAuth Loginto value ON for Facebook login app in Facebook developers console
