My Nest-wired doorbell is no longer ringing on the first button push. It now takes 4 - 5 pushes before it will ring. My electrician has looked at it twice now, and of course, it worked both times on the first touch for him. The video function on the doorbell is working fine with no issues and works perfectly on my iPhone. It's just the intermittent chiming that takes several attempts before the chiming begins. No visitor is going to ring a doorbell multiple times. it should work on the first button touch. My electrician has no idea how to fix the issue.
