Perhaps this is a Faulty Device?:
Set Up a Genus Bar Appointment:
By your description, this may be a faulty device. Note that you have a one-year, out-of-the-box limited-warranty with this. So, ask Apple to look at it, at the store Go Here: Genius Bar Reservation and Apple Support Options - Apple.
Contacting Appel Support:
Prior to brining this in, and prior to setting up the Genius Bar Appointment, contact Apple Support, asking them what is going on here.
Note: Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)
