Rachio 3 settings frustration

Seems the last couple of years my Rachio 3 does not work properly reading when it’s time to water. I have “extensively” set the variable for each of my four zones, yet Rachio does not water when necessary. Two of the fours zones always read “no upcoming watering” which isn’t true. The heat of August and waterings should be more frequent. I end up doing quick runs. I am very disappointed in the system. Having ready all the “articles” provided by Rachio for how to set up each zone, and spent much time studying how to do it, still not acceptable. Anyone else having frustrations as described. Btw…I don’t expect to get any response from Rachio. Most likely I will need to call to get satisfaction.
