Research direction

Start by reproducing the failure at InstanceID.getInstance(ctx).getToken(...), using the issue's UnsupportedOperationException as the initial symptom. Trace the InstanceID token path in the Java Android implementation and determine the missing context needed to diagnose it. Done requires a confirmed cause and a documented or verified resolution, but the issue provides no test or file location.
