Volume only half?

[Jenner]

Not sure if I've pushed a button I shouldn't have but my white noise pro now only plays all sounds at half volume. The slide bar at the button to change volume level is now "half full" in appearance as is the circle at the end of the bar. The rest of iPad apps etc play normally. iPad settings are normal. Any suggestions? Thanks

We added a volume slider into the settings (gear icon). Please check that volume.
