Experiencing the same problem. Alertmanager official Docker image version v0.21.0
Creating Silence matching all alerts (alertname=~".*"). After silence is saved I see all affected alerts below (about 50 matched). Configured dummy HTTP-webhook counter and set it as receiver in Alertmanager. I observe alerts still being sent to the receiver (both firing and resolved).
