Cannot use analogRead of GROVE interface with WiFi #14

ADC2 channel cannot be used when WiFi is in use. M5Camera uses the pins which cause analogRead() to fail as GROVE interface. So we cannot use some sensors which need analogRead()to use. I think it's kind of a product bug.

Is there any workaround? I'm using M5Camera model B with Grove Sound Sensor.
