- I have searched the existing issues.
- I have carefully read the documentation and verified I have added the required platform specific configuration.
Please select affected platform(s)
- Android
- iOS
- Linux
- macOS
- Web
- Windows
Steps to reproduce
- Prepare/find available server with web-socket support
- Open the example app on Android (the issue persist only on Android)
- The websocket channel will be connected automatically
- Everything will work as expected
- Click "Enable geolocator"
- Pings (and actual data) from websockets will throttle more and more until completelly muted
Expected results
I expect ping messages each 3 seconds from websocket channel.

Actual results
As soon as I enable Geolocator (or Google Maps) with accuracy set to "best," it breaks the connection more and more until it is finally completely muted.
