Hello!
- SDK Version: 35.0.0
- Platforms: iOS
We have an app with only webview and sometimes our website users get a crash of the app. It happens in production mode. In development mode we didn’t get such problem so far. The website has login with facebook / instagram and when someone try to login the app crashes itself. An example of log of one of the crashes:
