Description
### What is the issue?
When I start the Android app, it runs for a few seconds and then crashes. If I turn off wifi and mobile data, it won't crash until a few seconds after I turn either one back on. I have tried restarting the phone and uninstalling/reinstalling tailscale.
Using adb I retrieved this log:
