iOS app: Spatial Audio is stuck on

@TabloSupport recently I’ve become annoyed when remotely playing back recordings with the iOS app, because Spatial Audio (via AirPods Pro) is turned on and there appears to be no way to turn it off. This contradicts the iPhone settings, but I can clearly hear it - the Tablo sound appears to be fixed in one spot when I turn my head, then it drifts off-center - the very reasons why I studiously disable Spatial Audio everywhere, as often as I must (Apple seems to re-enable it with every OS update).
