Every night at around 3 / 4 AM my play 1 omits a low pitch ‘ping’ around a dozen or so times. They happen every 20 seconds or so.
At first I thought it was my Alexa so unplugged it to find out it must be the Play 1 in our kitchen.
It is a mid / low pitch ping that lasts a split second and repeats around a dozen times. Wakes me up every night, any help appreciated.
