Hi, My sleepbuds are making a weird (single) "Ping" sound in the middle night, which (ironically) wake me up each night. It seems to happen just once a night, but at seemingly random times. I've checked every setting in the app for what this sound could be, but I'm unable to figure it out. The battery level is at about 80 to 90% every morning, I don't have the low battery warning set, I don't have an alarm set, and I'm using the latest firmware. Does anyone have any clue what this sound might be, and how turn it off? Thanks. Regards.
