Where is the documentation on how to use the app? I have no clue how to set my own schedule or how to use the smart scheduling... I can't find anything on how to use this app at all and it's pretty confusing. I am looking at the app and it seems to have smart watering enabled, but there are times where it's skipping 3 days randomly and there is no rain that is supposed to take place on those days, so no clue why it's skipping those days. Can someone direct me to where the documentation is for using the app?  Thank you.
