White noise stopped working.

We have 2 nanit cameras. The white noise has stopped functioning on one of them. The other one still has functioning white noise. The one without functioning white noise is a nanit plus.

I have tried power cycling this nanit. I also have uninstalled and reinstalled the app while power cycling the nanit (and also power cycling my phone). I have also tried completely resetting the nanit and pairing it to my account again. All of this has had no success.
