The toolbar's mute buttons depict respective features/base/media states. However, (un)muting is practically carried out by features/base/tracks. When the mobile app enters a conference configured to invite the joining participant to mute themselves, the tracks would be muted but the toolbar's mute buttons would not reflect that.
