I have watering restrictions and utilize the Manual skip to manage within the guidelines. I have Flex Daily set. The Manual skip button is not available on many days recently. It will show up on some days but not others. An additional issue I have had recently is that I have set a Manual Skip but the program watered anyway.
Manual schedule skip is only supported on the “next” watering day, nothing else in the future.

That’s extremely annoying. I know there’s fog (enough for everything to be soaked) for the next week and I need to turn off watering, but can’t just skip, I have to shut the whole thing down. Which sucks, esp if you’re travelling with intermittent cell service.
