Crash after setting notification icon to none
Mi Band Notify 6.8.3 PRO without Mi Fit
Mi Band 3 with fw 18.104.22.168
Samsung S8+ / Android 8.0
After setting any notification's icon to none and saving, the app force stops. Any attempt to edit the notification afterwards results in another force stop. You can delete the notification and create it again with an icon, but you cannot do that for battery low/charged notifications (I had to reset the settings).
