Webview Issues

I have updated to 1.81 and I am still having issues with Android Webview. I have read the docs several times and searched this forum for fixes, but none to help. Been going on for a few months now. I get: Uncaught (in promise) FirebaseError: Messaging: This browser doesn’t support the API’s required to use the Firebase SDK. (messaging/unsupported-browser)

I have no idea what to do. I have redone things on my end as well, tried to disable other plugins also. It works fine on the browser.
