No, I see microphone picture in the bottom part of the screen (with animation). And its just some notes are missing. Overall microphone input is working.

Using iPhone 8 Plus. In sight-singing exercises EarMaster cant hear me singing some (only some) notes. At first sensitivity was great but later with app update it became worse. Using corded EarPods. I have to hold mic near my mouth and still sometimes need to shout (some notes) for EM to hear me.
