Yeah, same problem on Android. Sometimes you get notifications of watering finished sometimes you dont. Some times it shows up in the calendar sometimes not, sometimes in watering history sometimes not. Very sporadic. I worked with tech support last year and they said an app update would fix it but then it got cold and I didn’t water, but now I started again and same problems. My install is in a remote location so I never know for sure if it watered or not….I have to drive there to verify. Very aggravating.
