-I have updated with your code set up and it works well in testing phase.
-My app.json file is in format with what you have shown me.
-I deleted manual addition of metadata in the node modules to set it back to default.
-But in actual google play bundle even with the update it again crashes at set up.
-admob docs
Here it saids “web” is not supported for admob expo.
-adamjnav the admin told me on another post that webview is part of web and must be
web-supported to work webview admob
So my guess is that webview for admob not being supported is auto crashing the app or it may still be something else
