I haven’t seen this covered yet so I apologize if this already was.
I do not own a Wyze Band, but in the last few days a notification bar on upper left corner of my phone reads “Band connection is running” and doesn’t go away. Not clickable either.
Tips anyone?
Bump – Anyone?? lol
I’ll assume you’re using an Android 9 or 10 phone…
Pull down the status bar from top of screen.
Long press the notification.
Turn off this undesired notification by tapping the on/off toggle.
or…
Go to system settings.
Open Apps.
Scroll down to Wyze and open it.
Open Notifications.
Turn off “DownChannelService” and “WyzeBandService” by tapping the on/off toggles.
And you may wish to restart your phone after doing this.
Thank you friend!
Applied method #1 I wasn’t sure if “DownChannelService” was critical to have for other non-band related updates or notifications.
No prob… glad to be of help. 
“DownChannelService” is related to the Alexa service.
Thanks for clarifying
