Thanks for this, was able to reproduce the first issue and will submit to development team.
Zone 3 is shrubs, which by default have a 15 inch root zone depth, which means deeper watering but less frequent. If you look at the zone card the next scheduled day is July 12, based on predicted weather.
Shrubs are harder to use in flex since a lot of people have mixed zones, and not all shrubs are the same (root zone depth,etc.) Hope this helps!
Please use this form in the future to submit feedback, easier to track these, thanks for being a beta tester!
