I had schedules already created for flex, but wanted to try the as needed thing. I saw that it was going to run right away so I put in a rain delay. When I was ok for it to run I removed the delay and topped off the zones that didn't need water... which were completely ignored in as needed.
Not a typical use case for a first time user, but it is a typical use case. I have 2 zones that are shady. I would have had to move them to another schedule to fix things
Franz hooked me up with the beta app and I am all good now.
