When calling ConnectionsClient#startDiscovery(String, EndpointDiscoveryCallback, DiscoveryOptions) on my OnePlus7Pro (Android 10), I get
com.google.android.gms.common.api.ApiException: 8036: unknown status code: 8036

I don't think this is a problem of my code. The code works fine for any other Android version. The same thing happens on the official sample https://github.com/android/connectivity-samples/tree/master/NearbyConnectionsRockPaperScissors and can be reproduced there by adding a failure listener.
The error is not defined in the docs https://developers.google.com/android/reference/com/google/android/gms/nearby/connection/ConnectionsStatusCodes. Advertising works fine.
Any idea what the error means and how to get rid of it?
This status code means that the ACCESS_FINE_LOCATION permission was not requested at runtime, but this permission is now required by Android 10 in order to discover.
See https://developers.google.com/nearby/connections/android/get-started to verify you have all the necessary permissions.
Our status code docs are out of date, so we will update https://developers.google.com/android/reference/com/google/android/gms/nearby/connection/ConnectionsStatusCodes to make sure all the status codes are included shortly.
