For the last couple of updates (around when the interface changed) I've noticed when I start the app, the sound is set to loud. This is a problem when I don't want to announce to those around me that I'm playing a game - e.g. on the train, or if my kids are doing homework.

If go into settings, then into Audio, the sound level sliders are still where I set them last time, but the game ignores the level of the slider settings (e.g. music and sounds both set to 0 or 1) and the sounds are loud regardless.

If I move the sliders and change the levels up and then back down to 1 or 0, then the game uses the new volume levels I've selected... until I save and exit the app and come back in again. Then again the sound is loud.
