Missing Ring alerts sometimes

Hello All, I am issue with my Ring Doorbell, as sometimes it fails to notify me that there is someone at the door. This only happens occassionally, but I have missed impotant deliveries and visitors. I have about 5 shallow steps that lead up to the front door. I have disabled the motion dectors, so that the camera does not in lookin for any motion, and hence will not be recording. Speaking to the technical team, they said it is because the bell is busy recording a motion and will not register any other event until 30 seconds. This sort of sounds ok ... but not sure why it is occasionally missing the event of the button being pressed. I am a little confused as this is a doorbell and I would assume the the pressing of the button would take priority over any other motion detection. It is still happening, so unless I can find a resolution, I will have to get rid of the doorbell, as it is clearly not functioning as a doorbell.
